Note:   Live birth rates are per 1,000 women per year.  1980-1999 population estimates have been revised by the Department of Management & Budget.  Total fertility rate is total children to 1,000 women in their lifetime assuming constant live birth rates.  Rates of live births to women aged 45 and over are per 1,000 women 45-49 years of age.
Source: Total live births for the years 1920 through 1959 were derived from outside sources. Live births by age of mother were not tabulated in Michigan prior to 1960. These data were obtained from the following sources:
1920-1923: Unpublished tables from the National Center for Health Statistics.
1924-1932: Bureau of the Census publication, Birth, Stillbirth and Infant Mortality Statistics for Birth. Registration Areas of the United States.
