GENERAL DESCRIPTION:

This dataset contains the US Census Bureau 2010 Census Block Groups for the State of Florida with selected fields from the 2010 Redistricting Summary File and Summary File 1. Some of the fields included in this dataset are total population, age of the population, population by race, density and percentage of population by race, and household occupancy. This data is at the block group level. In addition, fields have been added and calculated. This data is designed for use within the Florida Department of Transportation s Efficient Transportation Decision Making Process (ETDM). However, the subset of redistricting fields included herein is useful for a variety of applications and uses. If you are looking for census block group data with complete attribute data in its original form from the Census Bureau, please see the FGDL layer CENBLKGRP2010_SF_AUG11.

The Florida Geographic Data Library is a collection of Geospatial Data compiled by the University of Florida GeoPlan Center with support from the Florida Department of Transportation. GIS data available in FGDL is collected from various state, federal, and other agencies (data sources) who are data stewards, producers, or publishers. The data available in FGDL may not be the most current version of the data offered by the data source. University of Florida GeoPlan Center makes no guarantees about the currentness of the data and suggests that data users check with the data source to see if more recent versions of the data exist. Furthermore, the GIS data available in the FGDL are provided 'as is'. The University of Florida GeoPlan Center makes no warranties, guaranties or representations as to the truth, accuracy or completeness of the data provided by the data sources.

A note about data scale: Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modeling purposes. Please be sure you are using the best available data. 1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:125000 scale datasets are recommended for projects that are at the regional or state level or larger. Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation.

DATA LINEAGE SUMMARY:

The Redistricting Summary File was downloaded from the Census in .pl format from http://www2.census.gov/census_2010/01-Redistricting_File--PL_94-171/Florida/ and the database was compiled using the process steps in http://www.census.gov/rdo/pdf/0HowToUseMicrosoftAccessShells.pdf The 2010 TIGER line files were downloaded from the following site: http://www.census.gov/geo/www/tiger/tgrshp2010/tgrshp2010.html When received the data was in Geographic Lat/Long projection. The data was projected to Albers HPGN. The data was then joined to the 2010 Tiger/MAF shapefile based on the GEOID10 field. Selected fields (see below) were renamed to be similar to naming from 2000 FGDL census data fields and duplicate fields were deleted. The following fields were extracted from the tables and renamed: P0010001 - TOTAL POPULATION P0010003 - WHITE ALONE P0010004 - BLACK P0010005 - AMERICAN INDIAN P0010006 - ASIAN P0010007 - NATIVE HAWAIIAN P0010008 - SOME OTHER RACE P0010009 - 2 OR MORE RACES P0020002 - HISPANIC OR LATINO P0020003 - NOT HISPANIC OR LATINO P0030001 - TOTAL POPULATION 18 YEARS AND OVER H0010001 - TOTAL HOUSING UNITS H0010002 - OCCUPIED H0010003 - VACANT The following QaQc procedures were performed: -exported original shapefile to file GeoDatabase -FGDLAQDATE added based on date GeoPlan acquired data from source -Added PCT and DEN fields based on calculations defined in attribute definitions -Changed name from tl_2010_12_bg10.shp to CENBLKGRP2010_MAR11 Process Date: 201103
