Average Total Sales Price on Zip-code Level in NYC (2003-2023)

To capture these geographic dynamics, I created a geospatial map illustrating the average total sales price at the ZIP-code level from 2003 to 2023. Each ZIP code is shaded in varying intensities of red, with darker shades representing areas with higher average sales prices. The map provides a granular view of geographic disparities in property prices, highlighting high-value neighborhoods such as those in Manhattan and parts of Brooklyn while showing more affordable areas in the Bronx and Staten Island. To enhance the functionality of this map, I added the hover-over tooltips, zip code, to reveal the details information, such as the specific zip code and its corresponding average sales price. Users can also refine the map by selecting specific property types using the “building class” filter or adjusting the timeframe using the “sale date” filter.
