Population
and Growth Trends The fastest growing population groups are adults over the age of 45 and children under the age of 14. The median age in 2000 (35.6) was slightly less than that of the entire county (36.0 years). The growth of the white population slowed somewhat as minority populations gained a greater percentage of the population in 2000. In terms of household makeup, the number of single parent families with children under the age of eighteen increased 26.3% between 1990 and 2000. The average household size in the sector has continued to decrease from 2.9 in 1980 to 2.44 in 2000. The increase in the number of dwelling units has corresponded with population growth. In the last decade, 24.6% of the county’s new dwelling units were located in this sector. Following trends throughout the county, single family attached units experienced the greatest increase, 230.1%, although single family detached units continue to comprise the majority of dwelling units, 64.4% of all units. |
