tr99_M_data: U.S. census tract data table for Alaska, Hawaii, and Puerto...

In satscanMapper: 'SaTScan' (TM) Results Mapper

U.S. census tract data table for Alaska, Hawaii, and Puerto Rico census tracts containing the projected coordinates of the state's census tract centroids.

Description

Contains the U. S. census tract information for Alaska, Hawaii, and Puerto Rico needed by the satscanMapper package to create the coordinates file to be used by SaTScan (TM). The main coordinates and boundary files were modified to shift Alaska, Hawaii and Puerto Rico to better positions on the US map. To be able to create a coordinates file based on the location IDs in the *.pop and *.cas input files to SaTScan (TM), the coordinates must be based on the original Lat and Long and not the moved locations. This dataset contains the unmoved projected coordinates of the of the centroids for all of the census tracts in the three affected states. Once the analysis is completed, only the mapping coordinates are needed.

Usage

data(tr99_M_data)

Format

The information contained in the tr99_data data.frame is:

row.names

- character - 11 digit State/County/Census Tract FIPS code.

stID

- character - 2 digit state FIPS code containing the census tract.

plKey

- character - a placename key associated with the census tract. The key contains the state/county 5 digit fips code and the placename.

c_X_00 and c_Y_00

- integers - the X/Y cartesian coordinates of the center of the census tract based on an equal area projection in meters for the census year of 2000.

c_X_10 and c_Y_10

- integers - the X/Y cartesian coordinates of the center of the census tract based on an equal area projection in meters for the census year of 2010.

y

- integer - a bit string identifying the census years the census tract existed. If the value is 1 or 3, the tract existed in the 2000 census. If the value is 2 or 3, the tract existed in the 2010 census.

/br The tr99 M data contain the coordinates for all of the Alaska, Hawaii and Puerto Rico census tracts. /br The place names in the tr99_M_data structure are derived from the HUD.gov Census Tract to ZipCode crossover tables and the USPS.gov zip code database for the 2000 and 2010 census. Additional place name information was provided by NCI as a supplement.
