Questions: Marriage and Nuptiality

Question 1

Hajnal identified a distinctive 'European marriage pattern' west of a line from Trieste to St. Petersburg. What were its key features, and why was it demographically significant?

• A. Early universal marriage with high fertility, producing rapid population growth
• B. Late marriage (mid-to-late twenties for women) and a significant proportion never marrying, which limited exposure to childbearing and kept fertility below biological maximum even without deliberate family planning
• C. Widespread polygamy that reduced per-woman fertility by spreading male reproductive effort
• D. Strict religious prohibitions on remarriage after widowhood, reducing total exposure to childbearing

Answer: (B)

Hajnal's 1965 article identified Northwestern Europe as distinctive for its late female marriage age (often 24-26) and substantial proportions (10-20%) remaining permanently unmarried. Since most reproduction occurred within marriage, this pattern limited women's total exposure to conception and kept fertility well below its biological potential — a form of 'natural' fertility regulation operating through social norms rather than deliberate contraception. Eastern and Southern Europe, as well as most of the non-European world, had earlier, more universal marriage.

Question 2

The singulate mean age at marriage (SMAM) is calculated from census data on the proportion of people who are currently married at each age.

• T. True
• F. False

Answer: False

SMAM is calculated from the proportion never-married (not currently married) at each age. It estimates the average number of years lived in the single state among those who eventually marry, derived from the area under the curve of proportions never-married from age 15 to 50. Using 'currently married' would confuse people who are widowed, divorced, or separated with those who never married, producing incorrect estimates.

Question 3

Explain why rising cohabitation complicates the traditional demographic analysis of nuptiality and fertility.

Model answer: Traditional nuptiality analysis uses marriage as a proxy for exposure to regular sexual activity and childbearing. When cohabitation is rare and non-marital fertility is low, marriage patterns closely predict fertility patterns. Rising cohabitation breaks this link: couples may be exposed to childbearing without being married, and marriage timing no longer captures the onset of union formation. In countries where cohabitation is widespread (Scandinavia, France, much of Latin America), marriage rates and age at marriage become poor predictors of fertility. Demographic analysis must shift to studying union formation more broadly, including both formal marriage and informal cohabitation.

This is a live methodological challenge. Data systems that track only legal marriages miss a growing share of reproductive unions. Some countries now collect data on cohabitation through surveys and registers, but measurement remains inconsistent. The Second Demographic Transition framework (van de Kaa, Lesthaeghe) theorizes the rise of cohabitation as part of a broader shift toward individualism, autonomy, and the decoupling of marriage from reproduction.
