Denver and teh Front Range

Denver, Colorado on a winter's day.

At one mile above sea level in an arid region, Denver, the twentieth largest metropolitan area in the country, boasts that it has the nation's most highly educated population.

Metropolitan sprawl uses up more than space; both water and electricity are needed for urban life.

Because water and energy are needed to inhabit modern urban areas, David Pimentel has argued that it takes ten calories of energy, or the equivalent of oil to bring one calorie of food to the modern urbanite's table.

Denver's households are 47% occupied by people or families who rent & the median age was just over 33 years old. One in three people are between 25 and 35 years old there.

Denver City: Population in 2012: 634,265 (100% urban). Population since 2000: +14.4% >

Denver County is a consolidated city/county; so the population in 2012: 634,265 was the same as the city which in 2000 was 554,636 persons.

County owner-occupied with a mortgage or a loan houses and condos in 2010: 103,999
