System and method for mapping and comparing choroplethic housing statistics

A non-transitory computer readable medium having computer-executable program code stored thereon, such that when the program code is executed by a computing device, it causes the computing device to:

• access property data corresponding to a geospatial area;
• generate property data statistics from the accessed property data;
• receive user instructions to initiate multiple maps;
• for each of the maps initiated by the user, provide the user options to select a comparison category from among a plurality of available comparison categories and an aggregation level from among a plurality of available aggregation levels that each define divisions of the geospatial area for statistical aggregation;
• for each of the maps initiated by the user, in response to the user selecting a comparison category and an aggregation level for the map, determine, from the property data statistics, selected property data statistics that correspond to the divisions defined by the selected aggregation level for the map and to the selected comparison category for the map;
• for each of the maps initiated by the user, generate a thematic map image that illustrates the divisions defined by the selected aggregation level for the map such that their respective appearances depend on the selected property data statistics corresponding thereto;
• simultaneously display the thematic map image for each of the maps initiated by the user;
• while the thematic map images are being simultaneously displayed, receive a first user selection of a first division, which is one of the divisions that is displayed in a first map image, which is one of the thematic map images being simultaneously displayed, and in response to receiving the first user selection, automatically:
• generate a graph image that graphs the selected property data statistics that correspond to the selected comparison category for the first map and to the first division across time;
• and
• display the graph image together with the thematic map images initiated by the user;
• and
• while the graph image is being displayed together with the thematic map images, receive a second user selection of a second division, which is another one of the divisions that are displayed in the first thematic map image, and in response to receiving the second user selection, automatically:
• update the graph image such that it distinguishably graphs the selected property data statistics that correspond to the second division across time in comparison to the selected property data statistics that correspond to the first division, the selected property data statistics that correspond to the second division having not been included in the graph image prior to the updating of the graph image,
• wherein each of the maps may have a different comparison categories from each other.
