COUNTY POPULATION
The population of Clackamas County was estimated by the Census Bureau at 380,576 residents as of July 2008. That was an increase of 12.5 percent since the 2000 Census.
The 2000 Census recorded 338,391 residents in the County, an increase of 21.4 percent from the 278,850 residents in 1990. During the previous decade, the population increased by 15.3 percent from 241,919 in 1980.
According to the 2008 Census Bureau estimate, Clackamas County's population has increased since July 2000 from domestic migration (an annual average of about 3,165 more native-born residents arriving than leaving), natural change (an annual average of about 1,335 more births than deaths) and net international migration (an annual average of about 810 more foreign-born residents arriving than leaving). Therefore, immigration was the smallest component of population change, and it accounted for nearly one-sixth (16%) of the county’s population increase.
FOREIGN-BORN POPULATION
FAIR estimates the foreign-born population in Clackamas County in mid-year 2008 to be about 31,390 persons (8.2% of the population). This represents an increase of 30.3 percent from the 2000 Census and compares with an 11.1 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 16.4 percent share of the County’s current births is large enough to account for about 665 births a year. Combining the increase in the foreign-born population and estimated immigrant births suggests that immigration may be adding as many as 1,480 persons to the County’s population annually, which amounts to nearly three-tenths (29.1%) of the county’s annual average population increase.
The 2000 census recorded 24,100 foreign-born residents in Clackamas County. That was a 7.1 percent share of the overall population, which was lower than the share for the state (8.5%). The 2000 data showed an increase of 110.8 percent in the immigrant population since 1990, which compared with a 17.5 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 21.3 percent of the County's population increase.
In 2000, the Census recorded that more than two-fifths (43.3%) of the County's foreign-born population had entered since 1990. This was lower than the rate as for the state overall (50%). More than one-third (38.6%) of the foreign-born residents had become naturalized U.S. citizens. This was higher 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 9.6 percent. More than two-fifths (42.9%) of those persons admitted to speaking English less than very well.
In 1990, there were about 11,405 foreign-born residents in the County. That constituted a foreign-born share of 4.1 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.
