US Census Bureau: Longitudinal Employer-Household Dynamics Data https://lehd.ces.census.gov/data/ LEHD makes available several data products that may be used to research and characterize workforce dynamics for specific groups. The LEHD Origin-Destination Employment Statistics (LODES) used by OnTheMap are available for download below. Version 7 of LODES was enumerated by 2010 census blocks. Previous versions of LODES were enumerated with 2000 census blocks. Data files are state-based and organized into three types: Origin-Destination (OD), Residence Area Characteristics (RAC), and Workplace Area Characteristics (WAC), all at census block geographic detail. Data is available for most states for the years 2002-2015. To browse the LODES data files in their directory structure or to access them with a FTP program go to: https://lehd.ces.census.gov/data/lodes/LODES7/fl/ https://lehd.ces.census.gov/data/lodes/LODES7/LODESTechDoc7.3.pdf |
For the research and analysis of the 2010 Census Redistricting Summary File and Summary File 1 at the Census Block geography level. The data contains selected fields from the 2010 Census. Census Block Groups are geographic entities made up of Census Blocks and that are contained within the same Census Tract. Block Groups generally contain between 600 and 3,000 people, with an optimum size of 1,500 people. |

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. The University of Florida GeoPlan Center makes no representations or warranties about the quality or suitability of the materials, either expressly or implied, including but not limited to any implied warranties of merchantability, fitness for a particular purpose, or non-infringement. The University of Florida GeoPlan Center shall not be liable for any damages suffered as a result of using, modifying, contributing or distributing the materials. 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.

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 cenblk2000 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 -Added BLKCHANGE field based on data derived from the Census 2000 Tabulation Block to 2010 Census Tabulation Block Relationship File. This file is available as a text file for download from the US Census Bureau. -Added GEOID00 field from data taken from 2010 Census Tabulation Block Relationship File. This field links back to CENBLK2000 using the STFID field. -Changed name from tl_2010_12_tabblock10.shp to CENBLK2010_MAR11 --- Summary File 1 was downloaded from the US Census Bureau from http://www2.census.gov/census_2010/04-Summary_File_1/Florida/fl2010.sf1.zip and the database was compiled using the process steps in http://www2.census.gov/census_2010/04-Summary_File_1/0HowToUseMSAccessWithSummaryFile1.pdf The data was joined to CENBLK2010_MAR11 based on the GEOID10 field. Selected fields (see below) were renamed to be similar to cenblk2000 fields and duplicate fields were deleted. The following fields were extracted from the tables and renamed: P0020002 - URBAN P0020003 - RURAL P0120002 - MALE P0120003 - UNDER 5 YEARS P0120004 - 5 TO 9 YEARS P0120005 - 10 TO 14 YEARS P0120006 - 15 TO 17 YEARS P0120007 - 18 TO 19 YEARS P0120008 - 20 YEARS P0120009 - 21 YEARS P0120010 - 22 TO 24 YEARS P0120011 - 25 TO 29 YEARS P0120012 - 30 TO 34 YEARS P0120013 - 35 TO 39 YEARS P0120014 - 40 TO 44 YEARS P0120015 - 45 TO 49 YEARS P0120016 - 50 TO 54 YEARS P0120017 - 55 TO 59 YEARS P0120018 - 60 TO 61 YEARS P0120019 - 62 TO 64 YEARS P0120020 - 65 TO 66 YEARS P0120021 - 67 TO 69 YEARS P0120022 - 70 TO 74 YEARS P0120023 - 75 TO 79 YEARS P0120024 - 80 TO 84 YEARS P0120025 - 85 YEARS AND OVER P0120026 - FEMALE P0120027 - UNDER 5 YEARS P0120028 - 5 TO 9 YEARS P0120029 - 10 TO 14 YEARS P0120030 - 15 TO 17 YEARS P0120031 - 18 TO 19 YEARS P0120032 - 20 YEARS P0120033 - 21 YEARS P0120034 - 22 TO 24 YEARS P0120035 - 25 TO 29 YEARS P0120036 - 30 TO 34 YEARS P0120037 - 35 TO 39 YEARS P0120038 - 40 TO 44 YEARS P0120039 - 45 TO 49 YEARS P0120040 - 50 TO 54 YEARS P0120041 - 55 TO 59 YEARS P0120042 - 60 TO 61 YEARS P0120043 - 62 TO 64 YEARS P0120044 - 65 TO 66 YEARS P0120045 - 67 TO 69 YEARS P0120046 - 70 TO 74 YEARS P0120047 - 75 TO 79 YEARS P0120048 - 80 TO 84 YEARS P0120049 - 85 YEARS AND OVER P0130001 - MEDIAN AGE, BOTH SEXES P0130002 - MEDIAN AGE, MALE P0130003 - MEDIAN AGE, FEMALE P0170001 - AVERAGE HOUSEHOLD SIZE P0180005 - MALE HOUSEHOLDER, NO WIFE PRESENT P0180006 - FEMALE HOUSEHOLDER, NO HUSBAND PRESENT P0190008 - HUSBAND-WIFE FAMILY, WITH OWN CHILDREN UNDER 18 YEARS P0190009 - HUSBAND-WIFE FAMILY, NO OWN CHILDREN UNDER 18 YEARS P0190012 - MALE HOUSEHOLDER, NO WIFE PRESENT, OWN CHILDREN UNDER 18 YEARS P0190015 - FEMALE HOUSEHOLDER, NO WIFE PRESENT, OWN CHILDREN UNDER 18 YEARS P0350001 - FAMILIES P0370001 - AVERAGE FAMILY SIZE H0040002 - OWNED WITH A MORTGAGE OR A LOAN H0040003 - OWNED FREE AND CLEAR H0040004 - RENTER-OCCUPIED The following QaQc procedures were performed: -FGDLAQDATE recalculated based on date GeoPlan acquired data from source -Changed name from CENBLK2010_MAR11 to CENBLK2010_AUG11 Process Date: 20110818 |
