Colorado Population Chart
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 1861, the Colorado Territory population was declared at 25,371 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.
Colorado Population Growth
Although that was by far the biggest increase in population in decade terms, further significant rises followed this initial boom, 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 Projections
Many states in the US have shown growth at every census, but Colorado's population is actually growing faster now than it did during the 20s, 30s, and 40s. The current growth is already causing housing shortages and increased traffic as Denver and Colorado Springs try to address the increased immigration.
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. Some estimates have placed the 2040 population as high as 7.8 million.
