Abstract
Using West German panel data constructed from the 1988 and 1994/1995 wave of the DJI Familiensurvey, we analyze the stability and determinants of individuals’ total desired fertility. We find considerable variation of total desired fertility across respondents and across interviews. In particular, up to 50% of individuals report a different total desired fertility across survey waves. Multivariate analysis confirms the importance of background factors including growing up with both parents, having more siblings, and being Catholic for preference formation. Consistent with the idea that life course experiences provide new information regarding the expected costs and benefits of different family sizes, the influence of background factors on total desired fertility is strong early in life and weakens as subsequent life course experiences, including childbearing, take effect. Accounting for unobserved individual heterogeneity, we estimate that an additional child may increase the total desired fertility of women with children by 0.14 children, less than what conventional estimates from cross-sectional data would have suggested.
Résumé
Sur la base du panel de données d’Allemagne de l’Ouest constitué à partir des vagues de 1988 et 1994/95 de l’Enquête Famille “DJI Familiensurvey”, nous analysons la stabilité et les déterminants de la fécondité totale désirée par les individus. Une variation considérable de la fécondité totale désirée apparaît entre individus et entre interviews. En particulier, jusqu’à 50% des individus déclarent une fécondité totale désirée différente d’une vague d’enquête à l’autre. L’analyse multivariée confirme l’importance des facteurs de contexte pour la formation des préférences en la matière, y compris le fait d’avoir grandi avec ses deux parents, d’avoir plus de frères et soeurs ou d’être de religion Catholique. En accord avec l’idée que les expériences vécues apportent des informations nouvelles par rapport au coûts et bénéfices de différentes tailles de famille, l’influence des facteurs de contexte sur la fécondité totale désirée est forte au début de la vie, et s’affaiblit au fur et à mesure des expériences, y compris de la procréation. En prenant en compte l’hétérogénéité individuelle non observée, nous estimons qu’un enfant de plus pourrait élever la fécondité totale désirée par les femmes ayant déjà des enfants de 0.14 enfant, un résultat en deçà de ce que laisseraient supposer les estimations conventionnelles basées sur des données transversales.

Notes
Among West German women, for example, completed cohort fertility has fallen from 2.2 to 1.6 children per women between the 1935 and the 1956 birth cohorts, while the corresponding desired number of children is estimated to have declined from 2.5 to 2.2 (see Heiland et al. 2005, Fig. 1). Other studies report on the trends for specific countries or regions (e.g., Toulemon 1996, 2001 for France).
The predictive value of preference data has been controversially debated for at least four decades (see Blake 1966; Westoff and Ryder 1977; Westoff 1981; and Long and Wetrogan 1981 for early critiques based on U.S. data and Van Hoorn and Keilman 1997 and Hagewen and Morgan 2005 for recent surveys of this literature).
Notable exceptions are Freedman et al. (1965), Gisser et al. (1985), Miller and Pasta (1995), and Quesnel-Vallée and Morgan (2003). Freedman et al. (1965) study the characteristics associated with revisions in expected family size during the first two years of marriage among a sample of couples in the Detroit area interviewed annually between 1961 and 1963. Gisser et al. examined fertility preferences of married women in Austria interviewed in 1978 and 1981/82. Miller and Pasta study the determinants of fertility motivations and preferences in a small sample of married individuals from the San Francisco Bay Area. Unlike the present article, Quesnel-Vallée and Morgan do not focus on the determinants of fertility preferences but study the gap between birth intentions and subsequent fertility outcomes.
We note that attained fertility and wanted fertility could diverge if there are significant social influences that are reflected in attained fertility but not in wanted fertility. As discussed in Bongaarts (1990), actual and wanted fertility can also differ due to biological forces, chance, or competing objectives. Recent evidence from European populations shows that achieved family size falls short of the desired one rather than the other way around (Heiland et al. 2005; Noack and Østby 2002; Van Peer 2002; Symeonidou 2000; Van Hoorn and Keilman 1997).
To what extent individuals, on average, correctly anticipate the benefits and costs of having (a particular number of) children is unclear. Udry (1983), for example, argues that fertility plans are updated at each parity. Evidence from individuals’ retirement behavior, for example, suggests that individuals are able to formulate very accurate expectations regarding the timing of their retirement (Benítez-Silva and Dwyer 2005).
The Familiensurvey does not collect data on spousal family size preferences. While we do not limit our sample to individuals with partners, it would be interesting to control for spousal preferences given evidence that they have an independent effect on fertility preferences and actual fertility (e.g., Morgan 1985; Thomson et al. 1990; Thomson 1997; Van Peer 2002; Voas 2003). However, we do not expect this to be a major limitation for those respondents with partners since the instrument of wanted fertility that we use explicitly asks that individuals answer for themselves as discussed below in more detail.
Models that allow for non-linear effects have been used in a cross-sectional context (see e.g., Philipov et al. 2004 and Heiland et al. 2005) but these papers do not provide strong evidence against a linear specification. The advantage of our statistical approach over alternative strategies allowing for non-linearities is its ability to account for person-specific unobserved heterogeneity that may be correlated with the time-varying variables as discussed below.
The limitations of this estimation strategy are well-known. In particular, fixed-effects estimates may be considered inefficient as they do not utilize the variation across individuals. This also implies that the effect of time-invariant individual characteristics cannot be identified. For a more detailed discussion of the assumptions of fixed effect panel models see Wooldridge (2002).
Data from the most recent wave of the DJI Familiensurvey (2000) are not used in this study since the survey instrument on desired number of children does not compare to the earlier waves.
Since individuals living in East Germany were not sampled until after the reunification (they were sampled in 1994/95), the panel starting in 1988 does not contain respondents from East Germany. For details on the sample construction and the comparisons to census data see Bender et al. (1996).
Coombs (1974) introduced a scale of family size preference capturing a person’s first, second and third preference using a series of questions on the most-preferred, second-most-preferred, etc. number of children. Unfortunately, the present data do not permit construction of Coombs’ scale.
For further detail regarding the construction of the measure see Heiland et al. (2005).
Morgan (1981 1982) suggests that respondents who answer “don’t know” to questions relating to fertility intentions are an important group that should not be discarded. Unfortunately, in the DJI Familiensurvey a distinction between “don’t know” and missing for other reasons cannot be made. Hence, we do not include this group in our analysis.
Comparison with a similar measure in the 2001 Eurobarometer (EUROSTAT 2001) for West Germany suggests that this cut-off affects only about 1% of the respondents. The maximum number of children reported there is seven.
Studies have employed different instruments of fertility preferences but desired, intended, wanted, or ideal number of children, which are similar to the one used here, are most common. Ryder and Westoff (1969) compare responses to questions on desired, intended, and expected number of children among American women and find insignificant differences between intended and expected number of children and only slightly higher desired numbers of children. Freedman et al. (1959) find higher desired than expected fertility among West German adults in 1958, but their question on desired fertility is qualified by if financial and other conditions of life were very good, which suggests a more hypothetical situation where having children is less costly.
We emphasize that information from older respondents is of interest since it may provide an important contrast to test hypotheses about stability and the determinants of preferred family size. Specifically, individuals may be able to better assess the net benefits of a particular family arrangement later in life, especially if they have children. Hence, we expect their preferred number of children to be more stable.
We constructed five binary indicators to measure different levels of completed education at the time of the interview: (1) no high school degree, (2) lowest or middle track high school degree (‘Volks-/Hauptschule’ or ‘Realschule’), (3) lowest or middle track high school degree with job training/apprenticeship (‘Lehre’, ‘Berufsfachschule’, ‘Volontariat’, ‘Laufbahnprüfung’, or equivalent), (4) college preparatory (college track) high school degree (‘Fachhochschulreife’ or ‘Hochschulreife’) with or without training, and (5) college degree or higher (‘Fachhochschule’, ‘Universität’ or equivalent). The ranking is based on the level of general schooling (basic secondary=ISCED2A, upper secondary=ISCED3A, tertiary/college=ISCED5A/5B/6) differentiated by additional vocational or job training programs. The ISCED codes stand for the education attained according to the International Standard Classification of Education. A helpful summary chart of the German education system can be found on the web at http://www.ed.gov/pubs/GermanCaseStudy/chapter1a.html.
The Inglehart scale measures a person’s post-materialism by how he or she ranks two post-materialistic societal objectives (‘giving the people more say in important government decisions’ and ‘protecting freedom of speech’) relative to two materialistic objectives (‘maintaining the order of nation’ and ‘fighting inflation’). A strong priority for post-materialistic goals is expressed by individuals who select the two post-materialistic objectives first (‘PPM’). A strong materialistic view is expressed by ranking the two materialistic goals first (‘MMP’). Other combinations express different degrees of post-materialism that lie between these extremes.
Gisser et al. (1985, p. 51) find that upward revisions are more common than downward revisions among married Austrian women.
Gender roles are progressing only slowly in West Germany (e.g., Stöbel-Richter and Brähler 2005) and combining family and career is difficult for women here given these inflexible labor markets, traditional gender roles, and social policies that favor the male breadwinner and female homemaker arrangement (see Kreyenfeld 2002; Brewster and Rindfuss 2000; Chesnais 1996; Gauthier 1996).
Due to space limitations, we do not report the estimates for other age groups or men. We also note that the coefficients for some variables (regional dummies and post-materialistic views) included in the models are not reported here. The additional results are available upon request.
Given evidence of greater stability among those initially reporting two as desired, the preference data may be heteroskedastic as discussed above. To address this issue, we also calculated the robust standard errors for the FE estimates. The results did not change the inference presented here.
