Black Holes. Don't let the name fool you: a black hole is anything but empty space. Rather, it is a great amount of matter packed into a very small area - think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City.
Determine Census Tract Codes Based on Address. â¢ Key in an address here to find codes/names based on address. Census tracts within a county are identified by a 4-digit basic code between 0001 and 9999, and may have a 2-digit suffix ranging from .01 to .98; for example, 6059.02. The decimal point separating the 4-digit basic tract code from the 2-digit suffix is shown in U.S. Census Bureau printed reports and maps.
Please select the appropriate activity year for the address being geocoded. The tract definitions for 2015, and 2016 data are based on the 2010 Census, for 2017 data is based on the 2015 Census. It is critical that the correct activity year is selected when using the FFIEC Geocoding System. Census Updates.
