New Jersey Health Statistics, 2004 is part of a series of reports of vital events and other health data dating back to 1877.  This report presents selected New Jersey vital statistics for the calendar year 2004 and includes data on births, deaths, infant and fetal deaths, marriages, domestic partnerships, and divorces.  In addition, population estimates for the state by age, race/Hispanic ethnicity, sex, and county are presented.

In the 2004 report, the chapters on birth and death are each organized into three sections:  trend data, cross-sectional state data, and county data.

  • The median age of all mothers was 30.5 years and the median age of first-time mothers was 27.7 years. 
  • There were 6,968 births to teens (6.1% of all births) and the teen birth rate was 11.7 per 1,000 females aged 10-19 years.
