Natural increase is the difference between births and deaths in the county or region. Obviously, an area will increase in population if there are more births than deaths in a year (absent the influence of migration, discussed elsewhere in this report). The table shows the number of births and deaths for each of the Central Indiana counties, for the region, for the suburban part of the region and for Indiana. Indianapolis’ natural increase is larger than that of the suburban counties (7,198 compared to 5,351 in the eight suburban counties). Thus, if only natural increase were considered, Indianapolis would still be growing faster than the suburban counties.
Natural increase varies from place to place. Most of that variation is caused by the birth rate. Indiana’s overall fertility rate (births per 1,000 women ages 15-44)4 was 67. Among the counties, the highest rates are found in LaGrange (96.1), Adams (94.1) and Daviess (84.3) counties, where large Amish communities live. The lowest rates occurred in Monroe (37.1), Delaware (47.5) and Tippecanoe (54.8) counties, the sites of Indiana’s largest college campuses, with large numbers of child-deferring young women. 5 The fertility rate for Marion County (78.9) was considerably higher than the state average and was the highest among Central Indiana counties.
4 Please note the difference between the fertility rate and the birth rate. The fertility rate is the number of births per 1,000 women ages 15-44. The birth rate, which is a much lower number, indicates number of births per 1,000 in total population. Both numbers are useful.
