To what extent does women's substantive representation depend upon the sheer numbers of elected women? Activists and scholars often assert a positive relationship between the numbers of women elected to office and public policy outcomes that are woman-friendly and even feminist. The idea of a “critical mass” is the popular and compelling notion that increasing the numbers of women in politics will start a chain reaction, leading to a new dynamic favorable to women.1

Increasing the numbers of elected women in a legislature may even produce negative consequences. The possibility that an increase in women's descriptive representation might produce negative outcomes has not been considered in the literature. Sheer numbers of women might conceivably generate a backlash from male gate-keepers, impede cross-party legislative work among female legislators, or serve to advance individual women uninterested in (or hostile to) public policies concerning women. Furthermore, an increase in women's sheer numbers could increase the partisan, ethnic, and racial heterogeneity of elected women in a legislature, with potential concomitant increases in party discipline, dividing women by party, potentially provoking tensions involving the necessary constructions of cross-race, cross-ethnicity alliances among women. Electing more women could mean electing fewer women motivated by the absence of women in politics to “act for” other women or it may make no difference at all.9
In short, the processes by which increasing the numbers of women in parliaments will result in women willing to advance woman-friendly legislation have yet to be elaborated, assuming elected women are situated in contexts that would permit them to undertake such a project, even if willing.Electing a “critical mass” of women to a national legislature may be a necessary but insufficient cause of women's substantive representation. It is also possible that sheer numbers of women are not a necessary condition for legislating women's policy issues and that small numbers of women who are well-situated may be able to deliver women's substantive representation.10
What numbers, frameworks, conditions, and contexts govern the ability of women legislators to make a difference?This article examines the comparative political research on women's descriptive and substantive representation. First, we focus on the issue of sheer numbers with a review and critique of the literature that suggests that numbers are dispositive. We review the theoretical foundations of critical mass in women's public policy-making and consider the ways in which sheer numbers of female legislators might be theorized in connection to women's substantive representation. We then turn to a critical assessment of the empirical literature on the conditions of women elected to national legislatures and the major factors that facilitate policy-making on women's issues.
Based on our theoretical assessment and empirical critique, we map the conditions under which female legislators are most and least likely to have policy successes. We consider the range of potential interactions between sheer numbers of women, on one hand, and the legislative and political context, on the other, to identify the conditions under which elected women might maximize woman-friendly policy successes. We construct a range of conditions between the two extremes: sheer numbers of women as the sole factor predicting women's policy representation, and legislative and civil society contexts identified in the literature to have been conducive for women's substantive representation. We situate research hypotheses regarding these conditions and contextual factors for assessing the impact of each, discussing the interactive potential among seven key variables that we hypothesize should provide the greatest analytical leverage for assessing the impact of sheer numbers of women on women's policy outcomes. In doing so, we map possibilities for further development of theory concerning women's descriptive and substantive representation.
Defining Women-Friendly Public Policy
The most problematic component of theorizing the relationship between women's descriptive and substantive representation concerns establishing what constitutes, in comparative political research, women's issues.11
The idea of women's substantive representation hinges on the notion of some kind of shared experience among women that fosters a sense of common social or political interests.12 Because women's experiences are socially constructed and because they vary widely based on the specific processes of construction, women's issues differ from context to context, across and within states and across time.13 Women's issues in the U.S. in the nineteenth century included, for example, temperance, suffrage, child-labor, public libraries, etiquette, and children's discipline. At the same time in Britain, women's issues focused on women's rights as autonomous citizens in marriage, married women's property ownership, women's rights in divorce, and child custody. In Southeast Asia, women's issues include micro enterprise aimed at women; in parts of Africa and the Middle East, female genital mutilation, veiling, citizenship rights, and early marriage are the substance of political and social movements on behalf of women. In contemporary India, women's issues include dowry requirements, protection against domestic abuse, and employment discrimination, among others.14Basu 1995.
It is also problematic that the effects of gender may not be distinct from those of race and class. In other words, the intersectionality of gender with other identities may limit the applicability of a women's issues paradigm.15

See Mohanty, Russo, and Torres 1991.
In light of these challenges, definitions of women's issues tend toward the general. Carroll defines women's issues as those that “disproportionately become the responsibility of women as a result of the sexual division of labor” and as issues “where policy consequences are likely to have a more immediate and direct impact on significantly larger numbers of women than of men”.18

In research on legislatures, the definition of women's issue legislation also tends to be broad. Thomas, for example, uses a definition of “policies favoring women, children and families” as women's issues.21

aim to improve the quality of life of women and children via legislation focused in such areas as child and health care, education, and parental leave. While gender equality policies are concerned with the redistribution of status and power, care policies are concerned with the redistribution of goods, services and public funds.23
Bystydzienski 1995, 72.
Heath, Schwindt-Bayer, and Taylor-Robinson consider the way that Latin America legislatures deal with women's issues in terms of committees that “deal explicitly with women and one of the primary locations of gender inequality—the family and home (e.g., equality in the work place, protection against violence in the home).”24

There is also the problem of distinguishing subjective from objective interests and this is why much research on women's policy issues conflates women's policy with feminist policy.27
For example, Hernes uses the term “woman-friendly” to refer to gender equality and social policies produced by state feminism.28Hernes 1987.

Role equity issues are those that extend rights now enjoyed by other groups (men, minorities) to women. Role change issues appear to produce change in the dependent female role of wife, mother, and homemaker, holding out the potential of greater sexual freedom and independence in a variety of contexts.32
Gelb and Palley 1996, 6.
Mazur, although explicit in acknowledging her focus on feminist public policy, limits her study to women's policy issues that involve at least three of five criteria:
improvement of women's rights, status or situation to be in line with men's … ; reduction or elimination of gender-based hierarchies… ; a focus on both the public and private spheres or an approach that avoids distinctions between the public and the private; a focus on both men and women; and ideas that can be readily associated with a recognized feminist group, movement or individual actor in a national context.”33
Mazur 2002, 30–31.
Not all women's organizations or women's activism are feminist in the sense of challenging patriarchy; women often organize around nonfeminist and even anti-feminist goals.34
Instead, women's organizations can be distinguished from other types of organizations, not by a litmus test of feminism but by “the primacy of women's gendered experiences, women's issues, and women's leadership and decision making.”35Beckwith 2000, 437.
See, e.g., Conover 1988.
While we recognize these dynamics and acknowledge that women's movements and women's issues should not be conflated with feminism, we also acknowledge that nowhere in the comparative literature on women's substantive representation is a theoretical link established between women's movements that are non- or anti-feminist and the representation of issues that in an “immediate and direct way, are about women exclusively.”38
Reingold 2000.
Note that there are also women's organizations that are not expressly feminist but that have mobilized in support of women-friendly public policies concerning childcare and maternal benefits, among other policies. These include the National Council of Women (Ireland; see Connolly 2002, 254, n6); the Committee of Mothers (Russia; see White 2000); and housewives' associations in the Nordic countries (Dahlerup and Gulli 1985); see also the Women's Alliance (Iceland; Sigurdjarnardóttir 1998), the Women's Cooperative Guild of England, the Union feminisme civique et sociale of France and the League of Women Voters in the U.S. (Black, 1989).
In short, our focus is on the interactions between sheer numbers of women and conducive policy-making contexts, based on the empirical political research to date. Our purpose is to theorize these interactions to identify combinations of conditions that might be expected to offer the greatest possibilities for converting women's descriptive representation into substantive representation, in the context of democratic political systems. Empirical evidence supports a general claim that the number of women elected to political office has a positive impact in terms of women-friendly public policy.40
We identify three major sets of factors that provide the greatest analytical and explanatory leverage concerning women's substantive policy representation: sheer numbers of women, conducive parliamentary contexts, and conducive civil society contexts.Sheer Numbers and Critical Mass
Research on the influence of sheer numbers of parliamentary women rely primarily on Rosabeth Moss Kanter's foundational study of women in a male-dominated corporate environment. Because of the structure of Kanter's argument, political scientists have discussed the impact of sheer numbers in terms of a “critical mass” of women and in terms of threshold percentages that are predicted to shift (that is, increase) women's policy representation. Kanter argued that women would have little influence as individuals or as a group in mostly uniform situations and that because they are still subject to performance pressures, role entrapment, and boundary heightening as tokens in “skewed groups,” they would not be able to muster influence within the larger corporation until they reached a representational threshold of 35 or 40 percent.41
Kanter 1977, 966, 972–984.
Although Kanter hypothesized solely about women in her work, she suggested that a similar logic would apply to racial minorities in corporate settings (1977, 966).
Research on women in national and regional legislatures has established that where women constitute less than 15 percent of a legislative body, women's influence will be constrained at best. There appears to be general agreement that a critical range of between 15 and 30 percent of women in a national or regional body, from parties across the political spectrum, is necessary for women to influence the agenda or style of business within that body or its policy outputs.43
The impact of sheer numbers of women at the lower boundary of this critical range can be evaluated: women constitute 15 percent or more of the lower or single house members in 81 of the 185 nations about which the Inter-Parliamentary Union reported data.44“Women in National Parliaments,” as of October 30, 2005. www.ipu.org/wmn-e/classif.htm
Nations include Costa Rica, Spain Cuba, the Netherlands, Denmark, Finland, Norway, Sweden, and Rwanda, only two of which (Sweden and Rwanda) meet a 40 percent representational threshold. Note that eliminating the Scandinavian countries leaves only 5 nations in the 35 percent group. www.ipu.org/wmn-e/classif.htm
Nations by percentage of women in lower house of parliament (2005)

It is likely that the higher the percentage of women elected to a national legislature, the more conducive the conditions for women's substantive representation. In addition, because most empirical research has found a strong relationship between women's representation within leftwing parliamentary groups or caucuses, we expect that high numbers of leftwing women elected to national legislatures will similarly effect women-friendly public policy. These claims in the literature can be hypothesized as follows:
H1: Where the percentage of women elected to a national legislature is 15 percent or higher, women's substantive representation in policy terms will be greater than in legislatures with a smaller percentage of elected women.
H2: Where the percentage of women representing leftwing parties in a national legislature is 15 percent or higher, women's substantive representation in policy terms will be greater than in legislatures with a smaller percentage of women elected by leftwing parties.
These, we argue, are the two most powerful variables concerning any critical mass of female legislators and the impact of sheer numbers of women on public policy outcomes.
Political Contexts
Critical mass and sheer numbers, however, do not take into account the context within which elected women enact political representation. We argue that political context is the necessary condition for translating sheer numbers of women into women-friendly public policy. To map the relationship between descriptive and substantive representation, we need to take into consideration not only the numbers and characteristics of the elected women but also the political context within which the women legislators are positioned. The literature on women's substantive representation suggests two major contexts: parliamentary and civil society.
Parliamentary Context
Which party is in government and how electorally secure that party is may affect the likelihood that parliament will produce women-friendly public policy. The comparative political literatures on women's substantive representation, social welfare policy and feminist public policy concur on the contributions of leftwing parties to advancing women's issues.46
See, e.g., Banaszak, Beckwith, and Rucht 2003; Bashevkin 1985; Katzenstein and Mueller 1987; Lovenduski and Norris 2002; Nelson and Chowdhury 1994; Threlfall 1996.
Any categorization of parties as leftwing is time- and nation-specific; we do not attempt such classification here. For an attempt to identify left- and right-wing parties, see Gabel and Huber 2000.
H3: Where the governing party (or coalition of parties) is leftwing, women's substantive representation in policy terms will be greater than in legislatures governed by center or center-right parties.
Second, it is important to consider the position of the governing party: is the governing party a long-standing governing party with a weak opposition, or is the opposition a credible threat to the government and well-positioned for the next election? Where a leftwing party is secure in government, in electoral terms, female legislators should have their best chances for enacting women-friendly public policies. Electoral security can be operationalized in several ways: the percentage margin of the vote won by the governing party/coalition in the previous election, the margin of seats secured by the governing party/coalition in the previous election, and public opinion approval ratings of the governing party/coalition. We subsume all these operationalizations in the following covering hypothesis:
H4: The stronger the electoral position of a leftwing governing party or coalition, the higher women's substantive representation in policy terms will be than where the government's electoral position is precarious.
Civil Society Context
Women and politics research indicates the importance of an active feminist movement in civil society articulating women's issues and insisting upon legislative action.49
Baldez 2002; Basu 1995; Banaszak, Beckwith, and Rucht 2003; Howell and Mulligan 2006; Htun 2003; Katzenstein and Mueller 1987; Mueller 1988; Threlfall 1996; Weldon 2002, 2006.
H5A: The more active a feminist movement in support of women's policy issues, the higher women's substantive representation, than where a feminist movement is weak or nonexistent.
There are, however, negative implications of feminist movement activism, specifically in the activation of opposing movements.50
See Beckwith 2002, 2003; Studlar and McAllister 2002; Luker 1984; Mansbridge 1986; Baldez 2002; Buechler 1990, Meyer and Staggenborg 1996; Tarrow 1998.
H5B: The more active a countermovement in opposition to women's policy issues, the lower women's substantive representation, than in a nation where a countermovement is weak or nonexistent.
Finally, support for women's issues in public opinion, especially among the mass of women, should provide a positive context for their substantive representation. Feminist movements often make claims based on women's public opinion to encourage legislators and political parties to adopt their policy agenda.51
H6: The more support women's policy issues have in public opinion, the higher women's substantive representation, than where public opinion does not support women's policy issues.
Mapping the Numbers/Context Intersection
Mapping these seven factors provides a way to assess the impact of critical mass against sheer numbers, in specific political contexts. These seven factors are mapped interactively, albeit not exhaustively, in table 2. Although each factor should facilitate substantive policies for women, not all are necessary for substantive representation to occur. Instead, several combinations of intersecting factors are likely to effect women's substantive representation.
Conditions facilitating women's substantive representation

Table 2 maps five exemplary sets of intersecting factors with the potential to predict women's substantive representation. The first column of table 2 indicates the maximum facilitating conditions for women's substantive policies (Case 1). All seven facilitating factors are present: many women are in office, especially in left parties; there is a secure, leftwing government, with strong support from an active women's movement and from public opinion more broadly. In short, Case 1 relies on large numbers of elected women in the most auspicious context, hypothetically resulting in high levels of women's substantive representation. Although the intersection of these measures of numbers and context is likely to be rare, and data on some of the conditions are not available, Scandinavian parliaments since the 1960s come closest meet these criteria. By the early 1970s, Denmark, Finland, Norway and Sweden had all crossed the representational threshold of 15 percent women in the national parliament.52
See Skard and Haavio-Mannila 1985, table 4.3, 62–63. In Finland, women accounted for at least 17 percent of all parliamentary seats by 1966.
Case 2 is one of few women but excellent conditions. In this case, of positive political context, a strong leftwing party governs with little effective opposition but with the support (or insistence) of a feminist movement encouraging women-friendly policy-making, and of women-friendly public opinion. Women's substantive representation is likely to occur under these conditions, even in the absence of sheer numbers of women. Examples of Case 2 can be found in the U.S. Congress, the German Bundestag, and the British Parliament in the late 1960s to the mid-1970s.53
In the U.S., the Democrats lost control of the executive in 1968 in the context of the ongoing Vietnam War, which though divisive, did not divert public attention from other social reform movements or martialize civil society.
Note that the British example is not a perfect instance of this case as there was significant and growing Conservative opposition to the Labour governments led by Harold Wilson.
The ERA never received sufficient support from the states to achieve ratification.
President Nixon vetoed the legislation, which Congress was unable to override.
The U.S. Congress averaged less than 3 percent women from 1965–1973; the British Parliament averaged approximately 4 percent from 1964 to 1974; and the FRG's Bundestag mean representation was approximately 6 percent from 1969 to 1976.
Case 3 is distinctive by virtue of the presence of women in two arenas: sheer numbers of elected women within parliament, and extra-parliamentary activist women in feminist movement in civil society. In this case of numbers and civil society, women are active and positioned within and outside government, in the absence of a leftwing governing party. Strictly speaking, elected women are present in relatively high numbers only within leftwing parties, for two reasons. First, no scholarly literature theorizes about the strong presence of rightwing women vis-à-vis women's public policy outcomes. Second, leftwing parties, excluded from government, are unlikely to hold a large number of seats and hence are unlikely to have elected enough members, let alone female members, to enable women's representation within the entire legislature to surpass the 15 percent representational threshold. This dual positioning, although not ideal, may nonetheless be sufficient to wrest some women-friendly public policy from national legislatures. For example, in Italy in the late 1960s and into the early 1980s, activist women in leftwing parliamentary parties, supported by a growing and militant feminist movement and by shifts in public opinion, were able to enact or sustain legislation concerning civil divorce, abortion, and employment opportunities for women.58
Beckwith 1987; della Porta 2003. Note, however, that women's parliamentary representation within left parties varied by party. The Italian Communist Party (PCI) consistently elected a higher percentage of women than did the Italian Socialist Party which, from 1963 through 1979, never managed to elect more than one woman (for a “high” of 1.8 percent of the PSI delegation). In addition, from 1968 to 1992, women in the PCI delegation met or exceeded the 15 percent representational threshold only twice: in 1976 (17.6 percent) and 1983 (20.3 percent).
Case 4 is a situation of numbers and parliament in which the sheer numbers of women are present and the left party is in a strong position in government, with little or no support in civil society. Although we map this theoretical possibility, no empirical examples are available among parliamentary democracies. The sole empirical example appears to be that of the former Soviet bloc states under communism. In these cases, women's equal legislative representation was guaranteed as a principle of communism, in the context of a single governing left party; the percentages of women sitting in national legislatures in the Soviet Union and in the Warsaw Pact nations were consistently higher than in other nations. Strictly speaking, no civil society existed, independent of state control, and hence there was no social movement sector, and no feminist or opposing movements. In most of these states, in fact, women's descriptive representation declined sharply after the collapse of communism, in part because it was not supported by sustained women's activism.59
These examples, however, fall outside the established democracies whose policies we seek to explain and address legislatures that had little to no policy impact; in this regard, the case is more a theoretical construct than an empirically operative one. A relatively large percentage of women are unlikely to serve in a democratically elected national legislature, leftwing government notwithstanding, in the absence of support from civil society. Similarly, women-friendly public policy is not likely to occur in parliamentary democracies in the absence of pressures from civil society.Case 5, that of sheer numbers only, represents a theoretical ideal-type for which, again, there is no empirical example. In this case, strong descriptive representation of women is countered by unfavorable parliamentary and civil society contexts. We include this case for two reasons. First, the absence of such empirical examples can be attributed to the causal connection between sheer numbers and the context variables. Favorable civil society and parliamentary contexts are themselves implicated with favorable numbers conditions. In the absence of a feminist movement, supportive public opinion, or a strong left-party to adopt the agenda of women's descriptive representation, women are not likely to be elected in large numbers to the assembly. This relationship between numbers and political context variables is well-established in the literature on women's descriptive representation.60
See Katzenstein and Mueller 1987; Kittilson 1999; Bystydzienski 1988; Gelb 1989; Studlar and Matland 1996; Lovenduski and Norris 1993; Norris 1993.
Second, Case 5 completes the mapping of cases across the seven factors and, to that extent, is an important theoretical construct. The theoretical contribution of its empirical invisibility is that, at some level, descriptive representation and substantive representation of women are deeply connected. It is empirically impossible, although theoretically conceivable, to have large numbers of women in a legislature where the other conditions for women's substantive representation are hostile. At some level, women actually embody women's policy issues, because when conditions are hostile to women's public policy issues, women are not elected to parliaments. Case 5—of sheer numbers of women in a politically hostile context—would be the least favorable, and least likely, case for women-friendly public policy.
Note that one final possibility has been excluded from this table: cases where none of the conditions obtain. That is, no women sit in parliament, no left parties govern, there is no feminist movement, and public opinion does not support women's issues. We have excluded this set of cases for several reasons which, while perhaps obvious, deserve mention. First, there is no explicit theorizing in the literature on women's policy issues or women's election to parliament concerning outcomes regarding women's public policy under these unfavorable conditions. It would be possible to do so, for example, insofar as these conditions might map to fascist states, which actually legislate in regard to women's issues but not in the direction we predict for favorable conditions.61
See, for example, fascist Italy under Mussolini and the development of rape provisions in the Codice Rocco.
See, however, Htun 2003.
Conclusions
We have developed a theoretical model that is parsimonious, testable in all democracies, consistent with existing empirical research, and supported by the available theorizing. There are many other variables suggested in the literature such as incumbency and newness, levels and capacity of party discipline, ethnic and racial diversity, access to leadership and legislative committee positions, attitudinal diversity among the women and their willingness to represent other women, political and electoral stability, institutional newness, design, and culture, the presence or absence of women's policy machinery in the form of an executive agency dedicated to women's issues, that might provide additional explanation for women's public policy enactment.63
See Childs 2001a; Beckwith 2007; Jeydel and Taylor 2003; Bratton 2002; Swers 2002; Cowell-Meyers 2003, 2001; Dobrowolsky 2003; Dodson 2006; Considine and Deutchman 1996; Kathlene 1994; Kenney 1996; Rosenthal 1998; Mazur 2002. Note that our project focuses on explaining women's substantive representation, not women's descriptive representation or the election of numbers of women, which would involve a list of antecedent variables well-established in the literature. See, e.g., Carroll 1994; Darcy, Welch, and Clark 1994; Matland 1998; Lovenduski and Norris 1993; Welch and Studlar 1990, 1996.
As suggested in the discussion of the cases, above, it is unlikely that a subset of cases can be mapped to every combination of sheer numbers and favorable contexts. Nonetheless, we advance table 2 as a site for plotting more specific hypotheses and applying case data. Among the five ideal-type cases we discuss, only two are likely to predict women's policy success: Cases 1 and 2, the maximum facilitating conditions and positive political contexts. An arrow diagram of these two cases reveals three possibilities of strong relationships between numbers and contexts.
ARROW DIAGRAM 1: DIRECT IMPACT OF CIVIL SOCIETY FACTORS ON WOMEN-FRIENDLY PUBLIC POLICY

ARROW DIAGRAM 2 (Case 1): CIVIL SOCIETY FACTORS AS ANTECEDENT TO SHEER NUMBERS + POLITICAL CONTEXT, WITH THAT COMBINATION DIRECTLY EFFECTING WFPP

ARROW DIAGRAM 3 (Case 2): CIVIL SOCIETY FACTORS AS ANTECEDENT TO POLITICAL CONTEXT ALONE, WHICH THEN DIRECTLY EFFECTS WFPP

In these models, we understand civil society context as antecedent both to sheer numbers and to political context; we also model civil society as directly affecting public policy. Two major paths, therefore, predict women's public policy outcomes: one directly through civil society, where the pressure from public opinion and feminist movements, in the absence of opposition, persuade (male) legislators to act for women (Case 2); and a second path indirectly from civil society through combinations of agency represented by favorable political conditions of leftwing governments with little opposition or sheer numbers of women (Case 1).
As data are mapped to these diagrams and to the table, competing impacts concerning sheer numbers and critical mass explanations should become apparent. A critical mass impact, relying on a percentage threshold, should emerge as a sudden or dramatic increase in women's public policy; as the percentage of elected women increases from one election to the next (in parliament as a whole or simply in a major leftwing party), a step change should not be evident until the percentage of elected women meets or surpasses the critical representational threshold. In contrast, the impact of sheer numbers can be evinced in two ways: within a nation across time, or across nations. First, as the percentage of women in a single nation's legislature increases across time, there should be a concomitant increase in women's public policy. Second, among nations with a high percentage of women in their legislatures, public policy in women's interests should be high; nations with a small percentage of elected women should have little success in legislating on women's policy issues. Similarly, women-friendly public policy is not likely to occur in parliamentary democracies in the absence of pressures from civil society, particularly in the absence of an organized feminist movement.64
When and under what conditions does women's substantive representation occur? Drawing from the comparative literature on women-friendly public policy, we have proposed a means to predict women's representation in policy terms. In doing so, we take the claims of critical mass theory and contextualize them in other explanatory variables, showing the limits of the sheer numbers claim but demonstrating a way to approach the relationship between women's descriptive and substantive representation. Our purpose is to advance the theoretical discussion of the link between women's elected representation and women-friendly public policy beyond the idea of critical mass and open up avenues for further research into how women's interests are advanced in the policy process.
