What these data tell us:
Larimer County's population grew by approximately 17% between 2000 and 2009. This increase can be attributed to domestic migration (25,624 more residents having arrived than left between 2000 and 2009), natural change (17,456 more births than deaths between 2000 and 2009) and international migration (5,008 more residents having arrived than left between 2000 and 2009) [U.S. Census Bureau*]. Colorado's Department of Local Affairs Demography Office estimates that the annual population will increase each year by approximately 2% through 2019.*U.S. Census Bureau population estimates are different from DOLA population estimates due to different estimates methodologies. U.S. Census Bureau's 2009 population estimate for Larimer County was 298,382 compared to a DOLA population estimate of 294,970.

What these data tell us:
From 1990 to 2000, Larimer County's population grew at a faster rate (35.1%) than that of Colorado (30.6%). Relative to the other nine most populated Colorado counties, the increase was most similar to Adams, Arapahoe, Boulder, El Paso and Weld counties. Denver, Jefferson, and Pueblo counties had much smaller increases than Larimer County (15% to 20%). Larimer County continued to rank as the seventh most populous county in Colorado, according to the 2000 Census. See the data table for more information on population growth in Colorado's largest counties.From 1990 to 2000, both Fort Collins and Loveland experienced an approximate 35% increase in population. The two other largest Colorado cities with a similar increase were Westminster and Longmont. See the data table for more information on population increases in Colorado's largest cities.
Following the 2000 Census, population growth in Fort Collins (15.9%) and Larimer County (17.3%) was slightly lower than Colorado's 18.2% increase between 2000 and 2009. The largest population increases for the same period occurred in Loveland (29.3%), Timnath (173.1%), Wellington (113.4%), and the Larimer County part of Windsor (846.5%).
Note: Percentage increases can be misleading when applied to smaller populations. In looking at Larimer County's smaller cities and towns, small increases in numbers of residents may translate into large gains in percentage of population increases.
