OBJECTIVES

  • Understanding of the role of demographic analysis and

information for private, government, and broad community uses

  • How demographic data are collected and compiled
  • The types of information that help put basic demographics into

perspective

WHAT DO WE USE DEMOGRAPHIC DATA FOR?

  • Constitution: Article 1,Clause 3: Apportionment of Representatives

and taxes

  • Representatives and direct Taxes shall be apportioned among the

several States … according to their respective Numbers, ….

  • The actual Enumeration shall be made within three Years after the

first Meeting of the Congress of the United States, and within every subsequent Term of ten Years, in such Manner as they shall by Law direct.

WHAT DO WE USE DEMOGRAPHIC DATA FOR?

  • Track social and economic change or progress
  • Allocate public resources and plan for the future
  • Important component of all social science:
  • Demography is the statistical study of human populations and sub-
  • populations. It involves the study of the size, structure, and

distribution of these populations, and spatial and/or temporal changes in them in response to birth, migration, aging and death.

SLIDE 5

WE ARE, HOWEVER, INTERESTED IN MUCH MORE

  • We also want to know about a population’s circumstances. Their

…

  • Economic well-being and sources of income
  • Ethnic or cultural characteristics (not religion)
  • Nativity
  • The characteristics of their housing
  • How they get to work
  • How they get along
  • These types of data are collected using survey information
slide-6
SLIDE 6

HOW DEMOGRAPHIC DATA ARE COLLECTED

  • U.S. Census Bureau
  • The Census: Decennial count (SF 1) is mostly limited to age, sex,

characteristics of households and families, race, Hispanic origin. It’s first use is in the apportionment of U.S. representatives, as well as

  • ur state and local legislative districts.
  • American Community Survey. A rolling and continuous survey of the

U.S. population that allows conclusions about the population, either using 5, 3, or one year averages

SLIDE 7

CONTINUED

  • The Current Population Survey (CPS), sponsored jointly by the U.S.

Census Bureau and the U.S. Bureau of Labor Statistics (BLS):

  • is the primary source of labor force statistics for the population of the United

States.

  • is the source of numerous higher-profile economic statistics, including the

national unemployment rate

  • provides data on a wide range of issues relating to employment and

earnings.

  • collects extensive demographic data that complement and enhance our

understanding of labor market conditions in the nation overall, among many different population groups, in the states and in substate areas.

OTHERS -- SURVEYS

  • Universities – General Social Surveys at the University of Michigan

Social Research Center.

  • Universities – the Iowa Farm Life Poll
  • Gallup, Roper, Pew and other long-term pollsters
  • Private firms, especially marketers, special interest groups, and

political organizations

  • State and local governments to fill information gaps or to deal with

extra-ordinary circumstances – local school districts often conduct special surveys

slide-9
SLIDE 9

PUTTING DEMOGRAPHIC DATA INTO PERSPECTIVE

  • Population characteristics
  • Age, sex, race, ethnicity, income, nativity, household composition,

mobility, education, workforce participation

  • More detailed understanding of the composition of households and

families

  • Income
  • Marital status
  • Presence and age of children
  • Poverty
  • Housing occupancy
slide-10
SLIDE 10

IMPORTANT COMPLEMENTS TO STANDARD DEMOGRAPHIC DATA

  • Vital Statistics
  • Births – natural gain

Plus characteristics of birthing population and birth outcomes

  • Deaths – natural decline
  • (Births - Deaths = Natural Change)
  • Fertility – plus characteristics of the birthing population
  • Marriage and divorce – population stability
  • Morbidity and mortality
slide-11
SLIDE 11

BIGGEST NEW ACTOR: THE AMERICAN COMMUNITY SURVEY

  • Continuous rolling survey – replaces the “long form”
  • Looks at us in great detail on an ongoing basis
  • Provides the foundation for a better understanding of socio-

economic attributes

  • Great confidence in findings for larger populations, but much less

confidence as the studied population declines

  • Is an average of several years (5, 3, 1). The more the years, the

greater the confidence, but the farther the data are from now.

  • Possibility of mischief and misinformation from misuse

THE ACS HAS BEEN ASSAILED IN CONGRESS IN RECENT YEARS

The sponsor of legislation to rid us of the ACS last year, Florida Republican Representative Daniel Webster proclaimed: The ACS “… is not a scientific survey; it’s a random survey!” In fact, the ACS provides some of the most accurate, objective and granular data about the economy and the American people, in something approaching real time. Ideally, Congress would use the information to make good decisions. Or economists and social scientists draw on the resource to offer better suggestions. Businesses also depend on the ACS's county-by-county statistics to inform investment and hiring decisions. As the great Peter Drucker had it, you can't manage or change what you don't measure. Republicans do themselves no favors by targeting a useful government purpose.
