Sales Tax currently represents a significant source of income to fund city services. Information on sales tax by segment provides data by economic category (e.g., transportation, retail, business to business, etc.) which can be measured to compare fluctuations in the market and local market conditions. This fluctuation can be affected by the number of establishments or the health of this particular category. For example, in the transportation category, the number of automobile dealers has a direct impact on the sales volume. Conversely, if the market is doing well, the revenues will also increase based on the volume of sales. Comparing by sales tax information by sector, economic segments at risk or economic segments that are expanding are more easily identified.
