DefinitionThe total fertility rate estimates the number of children a cohort of 1,000 women would bear if they went through their childbearing years experiencing the same age-specific birth rates occurring in a specified time period. It is calculated by summing the age-specific birth rates of women in five year age groups between 15 and 44 years, and then multiplying the sum by five.

Why Is This Important?The total fertility rate can be interpreted as a measure of how many children ''would'' be born to 1,000 women over their childbearing years, based on birth rates occurring in the present time. As such, it indicates the current capacity for human reproduction in the population.
Fertility is the ability to become pregnant and have a baby. Infertility occurs when a couple cannot become pregnant and may be related to a variety of health, behavioral, and/or environmental factors.
How Are We Doing?New Jersey's total fertility rate is 1,743 births per 1,000 women. This means that, based on today's birth rates, each woman would give birth to 2 children, on average, over her childbearing years.
The rate among Hispanic women is nearly 2,000 births per 1,000 women while rates among White, Black, and Asian/Pacific Islander women lie in the 1,500-1,600 range.
Over 70% of New Jersey's counties have total fertility rates below that of the state and the nation as a whole. Of the six counties with rates that are higher, Ocean County far exceeds all others with a rate (2,686.8) that is 1.4 times that of the second highest county, Passaic (1,960.1).
How Do We Compare With the U.S.?The total fertility rate among New Jersey residents has been below that of the nation as a whole for decades.
