What type of analysis would best answer the question, "How many fire stations are within each voter district?"

To determine how many fire stations are located within each voter district, a spatial analysis is the most suitable approach. Spatial analysis involves examining the locations of features on the Earth's surface and their relationships to one another. In this scenario, the goal is to assess the spatial relationship between fire station locations and the boundaries of voter districts.

By employing spatial analysis techniques, one can effectively overlay the geographic boundaries of the voter districts with the locations of fire stations. This may involve using tools that can count the number of points (in this case, fire stations) that fall within the polygons representing each voter district. This process allows for a clear and comprehensive understanding of how many fire stations are available to serve constituents in each district, highlighting both spatial relationships and geographical distribution.

In addition, while geoprocessing, statistical, and network analyses can each provide valuable insights in different contexts, they do not specifically focus on the spatial relationship needed for this particular question. Geoprocessing analysis is concerned with performing operations on spatial data, statistical analysis focuses on data interpretation through numerical methods, and network analysis pertains to evaluating connectivity and movement within a transportation or utility network. Therefore, spatial analysis is specifically tailored for the requirements of this question, making it the most fitting choice.
