Texas is the second largest country in geographical terms, with around 23 million inhabitants, and accounts for 8.69% of the population. In 2017, however, population grew by 1.43% in Texas and by only 0.61% in California.
Rhode Island, the smallest state, is actually more densely populated than a number of much bigger states, among them Montana, Alaska and Wyoming. Wyoming actually has the smallest population in the USA with just over half a million inhabitants. Montana, with its famed Big Sky, has almost ten thousand fewer inhabitants than the relatively small Rhode Island.
It is interesting to note that some of the major states had declining population in 2017, and Wyoming had the highest declining rate of all, almost 1%. Louisiana, Mississippi and Hawaii were other countries with declining population in 2017. Probably surprising, although Chicago is one of the biggest towns in the United States, the population of Illinois fell by 0.26% in 2017.
