COUNTY POPULATION
The population of Marion County was estimated by the Census Bureau at 314,606 residents as of July 2008. That was an increase of 10.5 percent since the 2000 Census.
The 2000 Census recorded 284,834 residents in the County, an increase of 24.7 percent from the 228,483 residents in 1990. During the previous decade, the population increased by 11.6 percent from 204,692 in 1980.
According to the 2008 Census Bureau estimate, Marion County's population has increased since July 2000 from domestic migration (an annual average of about 55 more native-born residents arriving than leaving), natural change (an annual average of about 2,260 more births than deaths) and net international migration (an annual average of about 1,450 more foreign-born residents arriving than leaving). Therefore, immigration was the second largest component of population change, and it accounted for more than one-third (35.5%) of the county’s population increase.
FOREIGN-BORN POPULATION
FAIR estimates the foreign-born population in Marion County in mid-year 2008 to be about 47,140 persons (15% of the population). This represents an increase of 31.1 percent from the 2000 Census and compares with a 7.5 percent increase in the native-born population.
Immigration also contributes to population growth through the children born to immigrants in this country. Nationally the share of births to the foreign-born is about double their share of the population. A 30 percent share of the County’s current births is large enough to account for about 1,410 births a year. Combining the increase in the foreign-born population and estimated immigrant births suggests that immigration may be adding as many as 2,860 persons to the County’s population annually, which amounts to more than seven-tenths (70.1%) of the county’s annual average population increase
The 2000 census recorded 35,969 foreign-born residents in Marion County. That was a 12.6 percent share of the overall population, which was higher than the share for the state (8.5%). The 2000 data showed an increase of 153.9 percent in the immigrant population since 1990, which compared with a 16.1 percent increase in the native-born population (which includes children born to immigrants) over the same period. As a result, the increase in the immigrant population accounted for 38.7 percent of the County's population increase.
In 2000, the Census recorded more than half (53%) of the County's foreign-born population had entered since 1990. This was higher than the rate as for the state overall (50%). About one-quarter (25.5%) of the foreign-born residents had become naturalized U.S. citizens. This was lower than the rate for the state overall (33.6%).
Another indicator of the impact of the foreign-born population may be seen in data on residents who speak a language other than English at home. In the County in 2000, the share of other-than-English speakers at home (age 5 and older) was 19.5 percent. More than half (56.7%) of those persons admitted to speaking English less than very well.
In 1990, there were about 14,160 foreign-born residents in the County. That constituted a foreign-born share of 6.2 percent of the population. By comparison, the foreign-born population shares of the Country and the state in 1990, respectively, were 7.9 percent and 4.9 percent.
