Brief history:
Las Vegas is a relatively young town but its history can be traced all the way back to 1829, when Antonio Armijo lead a party of 60 on the Old Spanish Trail to Los Angeles. While the caravan camped about 100 miles northeast of the present site of Las Vegas, a scouting party set out to look for water. Rafael Rivera, a young Mexican scout who left the main party and headed due west over the unexplored desert, discovered an oasis. The abundance of artesian spring water he found here shortened the Spanish trail to Los Angeles by allowing travelers to cut directly through rather than around, the vast desert. Spanish traders who used this route were thankful for the shortened trip and they named this convenient desert oasis Las Vegas Spanish for "the Meadows".
Las Vegas started as a stopover on the pioneer trails to the west, and became a popular railroad town in the early 20th century. It was a staging point for mines in the surrounding area, especially those around the town of Bullfrog, that shipped goods to the rest of the country. With the proliferation of the railroads, Las Vegas became less important, but the completion of the nearby Hoover Dam in 1935 resulted in growth in the number of residents and increased tourism. The legalization of gambling in 1931 led to the advent of the casino hotels for which Las Vegas is famous. American organized crime figures such as Benjamin "Bugsy" Siegel and Meyer Lansky managed or funded most of the original large casinos. The rapid growth of Las Vegas is credited with dooming the gambling industry development of Galveston, Texas; Hot Springs, Arkansas; and other major gambling centers in the 1950s.

My data range choice is 10 year each time, because it be more specific, so you can easier to know about the year that population rising strong, so I may know that in between 10 year, have something or some event that can make the population rising or falling. If I choose my data range is 20 year, it will be more harder to figure it out, so I choosing my data range is 10 year.
