According to the United States Census, Webster County's heyday occurred in the 1940's when over 18,000 people were residents of the county.
With one exception, it's been all downhill since then.
From 1940 to 1970, the population decreased to 9,809. Webster saw a bump in population to 12,245 in 1980 but by the time of the 2010 Census, Webster's population stood at 9,154.
By Census estimates, in 2015, Webster now stands at 8,755 residents. About 23 percent of Webster's population lives below federal poverty levels.
In its history, Webster has voted Democratic in every presidential election except in 1972 (when the county voted for Nixon over McGovern) and in 2012 (when the county voted for Romney over Obama).
