**3. DATASET ABSTRACT**

3.1 Abstract of the Dataset

The Time Series Demographic Statistics information (TSDS) (1970, 1980,
1990, and 2000) has been derived from Census Block Group Data common to
all four-decadal censuses. TSDS information covers the following general
areas, population, age, structures, racial and ethnic composition,
income distributions, employment, educational attainment, and
residential mobility. All data files are referenced to NOAA\'s Coastal
Assessment Framework. The data are available for five distinct spatial
aggregations: Census Block Group, County, State, NOAA\'s Coastal
Watershed, and USGS 8-digit Hydrologic Cataloging Unit.

3.2 Keywords for the Dataset

socioeconomic, economic, population, age, racial and ethnic
compositions, income distribution, time series demographic, block group,
coastal economics

**4. OBJECTIVES AND INTRODUCTION**

4.1 Program Objective

Special Projects (SP) is one of seven Divisions within the Office of
Management and Budget of the National Ocean Service (NOS). The mission
of Special Projects is to promote the NOS coastal stewardship mission by
providing NOS and its partners with integrated approaches to planning
and management, a national assessment capability complimentary to other
NOS programs, and an innovative program of information synthesis and
dissemination.

4.2 Dataset Objective

Many of the goals of those involved in coastal management and policy
include finding the balance in the coexistence of natural ecosystems and
human society, therefore a complete picture of the geographic patterns
of human activity and its relationship to the coastal environment is
needed. The Time Series Demographic Statistics information (1970, 1980,
1990, 2000) had been derived from Census Data common to all four-decade
censuses. The purpose of the time series demographic statistics data
files is to provide users with socio-demographic information such as
population, age, structures, racial and ethnic composition, income
contributions, and residential mobility in a format that facilitates
comparisons across time and space.

4.4 Summary of Dataset Parameters

The U.S. Census Bureau provides data for a range of geographic types
from the United States down to a Census Block. A detailed description of
Census geography terminology can be obtained from the U.S. Census Bureau
web site (American Factfinder -
<http://factfinder.census.gov/home/en/epss/glossary_a.html>).

The common variables that are available for the data aggregated by
Census Block Group, county, state, NOAA's Coastal Watershed, and USGS
8-digit Hydrologic Cataloging Unit are shown below.

6.2 Data Manipulation: Description

Georeferenced population points estimates were reported by Census Block
Group and/or Enumeration Districts. The points were imported into a GIS
system for quality control purposes and watershed assignments. Estimates
were assigned watershed attributes through a GIS overlay operation with
NOAA\'s Coastal Assessment Framework (CAF). The demographic variables
data were then summarized by NOAA\'s unique code, USGS 8-digit
Hydrologic Cataloging Unit (HUC) code and Watershed (EDA, CDA, FDA)
codes). Unique in the CAF is the intersection area of an 8-Digit
Cataloging Unit and Estuarine areas. County level estimates were
obtained by summarizing the demographic variables by the existent
5-digit FIPS code associated to each Census Block Group point data. Flag
variables were created to inform the user that a number of points fall
either outside of the county the point is supposed to be or on water.

To obtain the Time Series Demographic Statistic file (1970, 1980, 1990,
and 2000) only the variables common to all four census years were
obtained from each individual census file. The only exception to this is
the \"Year Structure was Built\" variable from the 2000 census is
included within these data.

in this study see the U.S. Census Data Calculations detailed project

**9. QUALITY CONTROL AND QUALITY ASSURANCE**

9.1 Measurement Quality Objectives

These data are reported in a separate file.

9.2 Data Quality Assurance Procedures

These data are reported in a separate file.

9.3 Actual Measurement Quality

The following variables for the 1980 Census were obtained from the
Geolytics CD due to problems with the accuracy of the 1980 source data
obtained from the Census Bureau: Nativity and Parentage (c80nativ,
c80forei), and Type of Structure and Tenure (c80tstr1, c80tstr2,
c80tstr3, c80tstr4, c80tstr5).

The total count of families for the 1980 variable Family Income (c80fi1,
c80fi2, c80fi3, c80fi4, c80fi5) does not equal the reported 1980 total
number of families reported elsewhere in this project.
