Changes in timing of fertility--a Canadian experience

Area of Science:

• Demography
• Reproductive Health
• Sociology

Background:

• Understanding childbearing patterns is crucial for population studies and policy.
• Fertility trends are influenced by socioeconomic and demographic factors.
• Analyzing birth timing provides insights into reproductive behavior.

Purpose of the Study:

• To examine the patterns and timing of births among Canadian women.
• To measure the intensity and timing of childbearing using advanced statistical methods.
• To compare birth timing patterns across different birth cohorts.

Main Methods:

• Utilized data from the Canadian Fertility Survey of 1984.
• Applied Semi-Markovian schemes to analyze maternity histories.
• Calculated age-and-duration-specific transition probabilities for childbearing.

Main Results:

• Identified distinct patterns in the timing of births.
• Quantified the intensity of childbearing across reproductive ages.
• Observed substantial changes in transition probabilities for recent birth cohorts.

Conclusions:

• Birth timing patterns have evolved significantly over time in Canada.
• Recent cohorts exhibit different childbearing dynamics compared to earlier ones.
• The findings highlight shifts in reproductive behavior influencing population dynamics.
