According to the 2000 Census, Webster County, Iowa has a population of 40,235 people. Of those, 37,574 (93%) are White, 1,364 (3%) are Black, and 944 (2%) are Latino. However, 1,256 (or 3% of the 40,235 people) are not residents by choice but are people in prison.
Even though prisoners cannot participate in the local community, the Census Bureau nevertheless counts them as residents of the county where they are incarcerated.
A more accurate description would not include the prisoners. This would give Webster County a population of 38,979 with a demographic that is 94% White, 3% Black, and 2% Latino.
The numbers for Whites, Blacks and Latinos may not add up to the total number because we have not included racial groups other than Whites and Blacks and because the Census Bureau considers "Latino" to be an ethnicity, not a race. Most of the people reported as being Latino are also counted as being White or Black.
