Block 1990 C Miami-Dade County
About This Dataset
This dataset contains the geographic boundaries of Census Blocks from the 1990 Census across Miami-Dade County. Census Blocks are the smallest geographic areas used by the U.S. Census Bureau to organize population and demographic data, with boundaries defined by streets, roads, and other visible features. While this is historical data from 1990, it's valuable for researchers, planners, and historians studying long-term demographic changes and understanding how Miami-Dade's population distribution has evolved.
Why This Matters
- A urban planner comparing neighborhood boundaries and population density between 1990 and today to understand how Miami-Dade has grown and shifted over decades
- A researcher studying historical census data who needs the exact geographic boundaries that correspond to 1990 Census records for their analysis
- A real estate analyst examining historical demographic patterns in specific neighborhoods to identify long-term trends in property values and community development
