Colorado Population 2016

The most recent official population count for Colorado was taken during the 2010 Census. At that time, it was found that the population was 5,029,196. This number has grown to an estimated 5,456,574 in 2016.

In the 2010 census, final numbers were declared at 5,029,196, a significant 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. This growth rate makes Colorado the third fastest-growing state in the US.

Colorado’s Population History

Historically, Colorado’s location in the middle of the USA made it a popular route for those traveling through the new world. Many liked the state so much that they chose to settle there, and the evidence of that is clear from the earliest censuses.

Back in 1860, the Colorado population was declared at 34,277 and ten years later, there had been just a modest rise of 16.3% to 39,864. However, by 1880 that figure had almost quadrupled and the census from that year reveals a total population of 194,327 -- an increase of 387.5% from the 1870 numbers.

Although that was by far the biggest increase in decade on decade terms, further significant rises followed, and by the beginning of the 20th century, Colorado’s numbers had grown to 539,700. In the latter half of the 1900s, increases in the region of 30% from census to census took the population of Colorado past the 5 million mark in 2012.

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 alone.

Colorado Demographics

From 2015 US Census Bureau estimates, the total Colorado Population can be divided as follows:

87.5% declared themselves to be White (68.7% Non-Hispanic White), 4.5% were Black or African American, 1.6% American Indian and Alaska Native, while 3.2% were Asian. The remainder of the population was split between other minority groups.

Colorado Population Projections

Like most states across the US, the population of Colorado is growing, but the growth has been significant in past years. Increases between censuses of 30% are not uncommon, and if that trend continues, the numbers could comfortably exceed 6 million at the next census in 2020, while some estimates have placed the 2040 population as high as 7.8 million due to young people moving to the larger cities within the state for job opportunities.
