According to election results from the Harris County Clerk's Office, Tuesday's election recorded the lowest voter turnout in Harris County in the last 20 years. On Nov. 7 only 6.7 percent of registered voters in Harris County voted. While voter turnout is typically low on odd years where there is no mid-term or presidential election, voter turnout this year fell below the previous low point of 8.83 percent in 2011. There was also no mayoral election this year, which typically increases voter turnout, like in 2015 when 20.51 percent of registered voters in Harris County voted. Although there were no prominent public office positions on the ballot, there were seven state constitutional amendments and six propositions totaling more than $1.5 billion in bonds for the city of Houston. All of the constitutional amendments and propositions for the city of Houston passed. Below is a chart comparing this year's voter turnout to previous odd years from 1997-2017. During this time, the number of registered voters in Harris County has increased from 1,680,542 in 1997 to 2,233,533, in 2017, an increase of about 33 percent. Source: Harris County Clerk's Office
