Front Range law enforcement agencies trying to keep up with Colorado’s population boom

... Denver’s population grew nearly 14 percent between 2010 and 2015 when 682,545 people were counted, and in 2015 Denver recorded the fastest-growing population among the nation’s largest cities, according to the U.S. Census Bureau. And city planners don’t expect it to slow down in the next 25 years...

 the Denver Police Department’s calls for service have increased 9 percent since 2006, with officers responding to more than a half million calls in 2015, according to statistics provided by the department.

Meanwhile, the number of officers dropped 6 percent to 1,441 from 1,539 during the same period...

CAIRCO notes

American women voluntarily achieved replacement level fertility (2.1 children per woman) in 1972. Yet mass immigration is driving U.S. population to double within the lifetimes of children born today.

The mass of people moving to the Front Range clearly does not consist only of legal immigrants - or only of illegal aliens for that matter. Yet we would suspect that as the illegal alien population of some states increases, the qualify of life decreases while the cost of living increases. It would be interesting to determine the proportion of newcomers to Colorado who escaped from California and similar states.
