For gas, let's assume you drive 1,000 miles a month and your car averages 23 miles per gallon. You'd need to budget about $87 per month with prices at $2 per gallon. That leaves only $124 for a car payment, parking and other transportation expenses.
North Dakota grew the fastest, increasing its population by 2.2 percent in the same time span. Colorado increased 1.9 percent. From 2010 to 2015, Colorado grew by 408,320 people, a 7.5 percent increase and the fourth-fastest growth rate behind North Dakota, Washington D.C. and Texas.
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. 1  Cities in Colorado. 2  Rank21. 3  2017 Growth Rate 1.82%. 4  Area in Miles (Rank)104,094 (8) 5  State CapitalDenver. 6  Statehood Year1876. 7  Red/Blue Blue.
