**The estimate has been suppressed because 1) The relative standard error is greater than 30% or when the relative standard error can't be determined. Consider aggregating years to decrease the relative standard error and improve the reliability of the estimate. 2) the observed number of events is very small and not appropriate for publication, or 3) it could be used to calculate the number in a cell that has been suppressed.

Fertility Rate

Fertility Rate: Live Births per 1,000 Female Population. The teen birth rate is considered an age-specific fertility rate. See also "General Fertility Rate," the number of live births per 1,000 women of child-bearing age (15-44).

An age-specific fertility rate is the number of births to women in a certain age group per 1,000 women in that same age group (e.g., births to adolescent mothers per 1,000 adolescent girls of the same age in the population).

Statistical Stability

Statistical stability, reported in the data table, is based on a statistic called the "Relative Standard Error," or RSE, which is the standard error expressed as a proportion of the point estimate (e.g., 30% of the point estimate). The following conventions are used here to interpret the RSE.[[br]][[br]] * A dash (-) means that the relative standard error (RSE) is below 0.30 and the count or rate may be considered stable. [[br]] Problems with statistical instability typically occur when there is a small number of health events in a small population. For more information on statistical stability, visit the MT-IBIS Reliability & Validity page []. [[br]][[br]]
