North Texas State Fair & Rodeo: The Economic Impacts of Existing Activities and Preliminary Feasibility Assessment for New Fairgrounds and Expo Center (open access)

North Texas State Fair & Rodeo: The Economic Impacts of Existing Activities and Preliminary Feasibility Assessment for New Fairgrounds and Expo Center

This report discusses the economic impacts of existing activities and gives a preliminary feasibility assessment for new fairgrounds and expo center. The economic and fiscal impacts generated by fairs, rodeos, horse shows, and cattle shows nationwide are significant. Impacts estimated in the millions of dollars are not uncommon for regional and state events. It is against this backdrop that the University of North Texas Center for Economic Development and Research has been asked to estimate the economic and fiscal impacts of the North Texas State Fair & Rodeo, as well as examine the potential market for and economic and fiscal impacts of building a new exposition center in Denton County. Later in this report, we will also examine the experiences of ten exposition centers across Texas and the U.S. that illustrate the types of events, and the associated costs, that would likely attend construction and operation of such a center in Denton County.
