Census results: Washington County grows 18 percent
Washington County remains the state's fifth-largest county, but it led the growth of first-tier suburban counties over the past decade, according to new 2010 census data released Wednesday.
Washington County grew from a population of 201,130 in 2000 to 238,136 last year. That addition of 37,000 new residents put the county's growth at 18 percent, higher than neighboring Dakota and Anoka counties.
Ramsey County saw a slight decrease in overall population in the past decade.
