During its thirty years of operation the District’s annual tax revenue has increased from $4,000,000 in 1972 to the current $68,000,000.  In 1972, approximately 63% of the tax receipts came from the County and 37% from the City.  In 2006, 85% of the tax revenue came from County taxpayers and 15% from those in the City. 

The expansion of the number of Sub-districts from three to five is indicative of the success and vitality of the original concept of a tax supported cultural district.  Today, the Metropolitan Zoological Park and Museum District is, perhaps, the largest tax supported cultural district in this country.  It is a model that other cities have often attempted to emulate.
