Between 1990 and 2000, the study area showed an approximately 8.7 percent increase in
the total minority population which was similar to both Santa Barbara and Ventura
Counties, which showed increases of 9.3 percent and 9.4 percent respectively. This data
indicates the region is becoming increasingly racially and ethnically diverse.
Age
As of 2000, most of the total population within the study area (15,341 persons),
approximately 62.5 percent (9,585 persons) were of working age, defined as between 18
and 64 years of age. Additionally, approximately 25.2 percent were under 18 years and
approximately 12.3 percent were 65 years and over within the study area as well as Santa
Barbara and Ventura Counties which has remained relatively constant.
Table 2.1-4 shows that, as of 2000, the age breakdown in the study area was similar to the
surrounding region. In Santa Barbara and Ventura Counties, the working age populations
constituted approximately 62.4 percent and 61.4 percent, respectively, of the total
population, similar to the study area at 62.5 percent. Additionally, within these same
regional areas, the population 65 years and older constituted 12.7 percent and 10.2
percent of the total population of Santa Barbara and Ventura Counties, respectively. The
population 65 years and older constituted approximately 12.3 percent of the total
population within the study area.
