GENERAL DESCRIPTION:
This dataset contains 2010 Traffic Analysis Zones (TAZ) as they are defined by the Bureau of the Census. The data contains selected fields from the 2010 Redistricting Summary File and Summary 1 file that includes, information on total population, race, sex, age, and household. A TAZ is a statistical entity delineated by state and/or local transportation officials for tabulating traffic-related census data. Traffic analysis zones (TAZs) are basic spatial units of analysis facilitating the ability of transportation planners to forecast changes in commuting patterns, trip volumes, and modes of travel, and to develop plans to meet the changing demands for transportation facilities and capacities. Each TAZ represents an area containing similar kinds of land use and commuter travel.

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

provided by the data sources. The University of Florida GeoPlan Center

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. For more information regarding

DATA LINEAGE SUMMARY: 








TIGER/Line Shapefiles are extracted from the Census MAF/TIGER database 
by nation, state, county, and entity.  Census MAF/TIGER data for all 
of the aforementioned geographic entities are then distributed among the 
shapefiles each containing attributes for line, polygon, or landmark 
geographic data.
Process Date: 2011


The 2010 TIGER line files were downloaded from the following site:
http://www2.census.gov/geo/tiger/TIGER2010/TAZ/2010/tl_2011_12_taz10.zip  
When received the data was in Geographic Lat/Long projection. 
The data was projected to Albers HPGN.

The 2010 Tiger/MAF shapefile was spatially joined to cenblk2010.shp 
and the following fields were dissolved and summarized:
POP2010
WHITE
BLACK
AMERI_ES
ASIAN
HAWN_PI
OTHER
MULT_RACE
HISPANIC
MALE
FEMALE
AGE_UNDER5
AGE_5_17
AGE_18_21
AGE_22_29
AGE_30_39
AGE_40_49
AGE_50_64
AGE_65_UP
MED_AGE
HOUSEHOLDS
HSE_UNITS

The spatial join output was joined back to CENTAZ2010.shp and the above 
fields were added and named to be similar to TAZ2000.shp fields. 

For fields MED_AGE, AVE_FAM_SZ, and AVE_HH_SZ, the Summary Statistics 
were obtained from the spatial join of CENTAZ2010.shp and CENBLK2010_AUG11.shp. 
The fields are the mean value of block level data summarized to the TAZ
geographic level. Zero values were not included.
--

The cenblk2010 shapefile contains data from the Redistricting Summary File and Summary File 1. 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
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

File tables and renamed:
