General Fertility Rate: Number of Live Births per 1,000 Women Age 15-44, 2021
Mercer53.6 95% Confidence Interval(52.0 - 55.2)Description of the Confidence IntervalThe confidence interval indicates the range of probable true values for the level of risk in the community.
A value of "NA" (Not Available) will appear if the confidence interval was not published with the NJSHAD indicator data for this measure.
Mercer Compared to State
Description of Gauge
Description of the GaugeThis graphic is based on the county data to the left. It compares the county value of this indicator to the state overall value.
The county value is considered statistically significantly different from the state value if the state value is outside the range of the county's 95% confidence interval. If the county's data or 95% confidence interval information is not available, a blank gauge image will be displayed with the message, "missing information."NOTE: The labels used on the gauge graphic are meant to describe the county's status in plain language. The placement of the gauge needle is based solely on the statistical difference between the county and state values. When selecting priority health issues to work on, a county should take into account additional factors such as how much improvement could be made, the U.S. value, the statistical stability of the county number, the severity of the health condition, and whether the difference is clinically significant.
- Excellent = The county's value on this indicator is BETTER than the state value, and the difference IS statistically significant.
- Watch = The county's value is BETTER than state value, but the difference IS NOT statistically significant.
- Improvement Needed = The county's value on this indicator is WORSE than the state value, but the difference IS NOT statistically significant.
- Reason for Concern = The county's value on this indicator is WORSE than the state value, and the difference IS statistically significant.
Why Is This Important?The general fertility rate is a more precise measure than the crude birth rate for tracking birth rate patterns. While the crude birth rate and the general fertility rate both look at the total number of live births among the population, the crude birth rate is calculated using the total population including the young, old, male, and female. The general fertility rate is calculated using only females of reproductive age, defined as ages 15 through 44 years, in the denominator. This results in a more sensitive indicator with which to study population growth and change.
How Are We Doing?The general fertility rate among New Jersey women was 57.9 births per 1,000 women of childbearing age in 2021. The rate varied widely across the state's counties from a low of 49 (Hunterdon) to a high of 98 (Ocean). Rates also varied by race/ethnicity. The rate among Hispanics (66) was significantly higher than the rates among other racial/ethnic groups.
NoteThe age range may be slightly different in some publications, so it is important to note what age range is being used especially if comparison with other rates is contemplated. Confidence limits are not available for national data.
