Mapping demographic data is a powerful tool for visualizing geographic and socioeconomic relationships across the U.S., providing insights into population density, income levels, and education across different regions. This process involves collecting data from reliable sources like the U.S. Census Bureau, selecting appropriate geographic boundaries, choosing relevant variables, and creating maps with platforms like Felt to visualize the data. By turning raw statistics into visual stories, demographic mapping helps identify gaps and opportunities in markets, aiding decision-making for businesses and planners by revealing underserved populations and areas of growing demand. Best practices for creating accurate maps include normalizing data to avoid misleading interpretations, choosing appropriate color scales, providing clear context and legends, and avoiding bias by ensuring a comprehensive representation of the data. Felt's tools allow for easy visualization, customization, and collaboration on demographic maps, transforming data into actionable insights for business strategies and policy decisions.
