Crystal Lake is a census-designated place (CDP) in Polk County, Florida, United States. The population was 5,341 at the 2000 census, an increase from 5,300 in 1990. The 2010 Census reported a population of 5,514. It is part of the Lakeland–Winter Haven Metropolitan Statistical Area.
There was a net migration of only 10 people to Crystal Lake in 10 years following 1990.
If the population went from 5300 to 5341 then only a net of 41 people came in. I think the system didn't like the big words that came in and the fact that I used only.
