Editing Cooper, Texas (section)

===Since establishment===
Cooper grew rapidly after being established, with a post office built in the community in 1871. Cooper was incorporated into a town in 1881 and held its first government elections. That same year, Cooper constructed the county courthouse. The town became the main market center for Delta County, and by 1885, Cooper had a population around 300. The Texas Midland Railroad, which ran through Cooper, was chartered in 1892. The railroad helped promote the rapid growth of the town. By 1896, Cooper's population had passed 1,000 people, and contained two churches, a school, and 21 businesses, including a bank and a hotel. The town also had two weekly newspapers. Cooper continued to grow into the early 1900s, especially in the area of agriculture. From the early 1890s to around 1910, farms boomed both in number and in value, with the number of cash crops nearly tripling. The region produced over 70,000 chickens and almost 7,000 pigs yearly.<ref name="Delta County"/><ref name="Cooper TSHA"/>

Cooper continued to grow into the 1920s. The bank had been rebuilt in 1909, and the region's crops continued to prosper. Cooper reported its largest population, 2,563, in 1925.<ref name="Cooper TSHA"/> Delta County was hit by the [[Great Depression]] early, though. In late 1926, the community's cotton crop failed, forcing many residents to withdraw their savings. The bank was forced to close in 1927, and by the time it reopened a few months later, the region's economy had plummeted. Several families moved away from Cooper during the early 1930s, and in 1933, the bank was forced to close again. The Midland Texas Railroad failed, hurting Cooper's economy further. The [[New Deal]] program offered government-financed construction projects in Cooper, and in 1940, the [[Works Progress Administration]] <!-- (WPA) --> demolished the former courthouse in Cooper and replaced it with a new one at a cost of $110,450 (equivalent to ${{formatnum:{{Inflation|US|110450|1940|r=-2}}}} respectively in 2022{{inflation-fn|US}}). However, even with the stability of the economy, Cooper's population remained low until the 1950s, when it returned to about 2,350 people. The population declined again in the 1980s, and has continued to slowly decline. Cooper had roughly 60 businesses in the 1970s and 1980s, and in 1986, work on [[Cooper Lake (Texas)|Cooper Lake]] had begun.<ref name="Delta County"/><ref name="Cooper TSHA"/> Filling of the lake began in September 1991, and by the next year, the lake was open for recreation.<ref name="Cooper Lake State Park">{{Cite book |last=Parent |first=Laurence |year=2008 |title=Official Guide to Texas State Parks and Historic Sites |location=[[Austin, Texas|Austin]] |publisher=[[University of Texas Press]] |edition=2nd |page=141 |isbn=978-0-292-71726-8}}</ref> At that time, Cooper reported having 70 businesses, and a population around 2,200. By 2000, the population had dropped by about 50 people and an estimate for 2016 is 1,957 inhabitants.<ref name="Cooper TSHA"/>
