All fertility, mortality, and migration assumptions have changed to better reflect conditions in 2007.
One other point needs clarification. In the 2000 Census, respondents were permitted to check up to six races. The projection process cannot cope with that differentiation since mortality, fertility, and migration rates would have to be calculated for very small groups. To avoid that problem, all multiple race individuals were reclassified to a single race based on preferences specified in local and national survey research results. The CDC all provided bridging information for the state and counties.
Finally, there are several categories on the summary page for the State and each county that require definition:
- Population Change - The net increase (decrease) in persons over the projected period;
- Births - The total number of births over the over the projected period;
- Deaths - The total number of deaths over the projected period;
- Net Migration - The total number of persons moving into the area less the number of persons leaving the area over the projected period;
- Household Change - The net increase (decrease) in households over the projected period, which is indicative of the number of housing units required;
- Jobs by Place of Work - The number of jobs held by civilians working in the area for the projected period excluding self-employed, private household workers, and those directly working on farms;
- Jobs by Residence - The number of jobs held by the employed persons for the projected period which will include the jobs of persons who hold more than one job;
- Net Commuting - The number of persons coming into the area to work each day less the number of persons leaving the area to work each day during the projected period;
