Colorado Population 2016
Our 2016 estimate for Colorado's population is 5,557,560. This estimate is calculated from projecting the most recent Census estimates. The last official population count for Colorado was taken during the 2010 Census. At that time, it was found that the population was 5,029,196.
The 2010 Census numbers represented a rise of 16.9% from the 2000 census survey, when 4,301,262 residents were shown to be living in Colorado. Updated estimates arrive on a yearly basis, and in 2015, it was reported that the numbers in Colorado had increased to 5,456,574.
The 2015 estimate reflects an 8.5% increase since the last census. With a yearly growth rate of 1.85% in 2016, Colorado is second fastest-growing state in the US.
Colorado Population Density
With a large surface area of 104,094 square miles (269,837 square kilometers) Colorado is the eighth largest state in the USA, but it is relatively sparsely populated. Some of the terrain is harsh, and the vast Rocky Mountain range accounts for a significant proportion of the state’s land mass.
As a result, there are 52 people per square mile (19.9 per square kilometer) and that makes Colorado only the 37th biggest state in terms of population density.
