Assessing the New Federalism (ANF)
  • Mission
  • To analyze the devolution of responsibility for
    social programs from the federal government to
    the states, focusing primarily on health, income
    security, job training, social services, and
    child well-being
  • To provide timely, nonpartisan information to
    inform public debate and to help state and local
    decision makers carry out their responsibilities
    more effectively

PART 1 Survey Overview
4
ANF Data Collection Strategies
  • 50 state database
  • Case studies on health, income support, and
    social services
  • National Survey of Americas Families (NSAF)

PART 1 Survey Overview
5
National Survey of Americas Families
  • Assess well-being of children, families,
    non-elderly adults within each focal state and
    across the nation
  • Three rounds of data collection
  • 1997 (files available)
  • 1999 (files available)
  • 2002 (files currently being released)
  • Assess changes in well-being over time at the
    state and national levels.

PART 1 Survey Overview
6
Sample Design Features
  • Nationally representative sample
  • Sample includes households without telephones
  • Includes all non-institutionalized residents
    under 65 (including non-citizens)
  • Representative samples drawn in 13 states
  • Oversample of low-income households
  • Defined as below 200 of the Federal Poverty
    Threshold
  • By default, oversample of racial and ethnic
    minorities, immigrants, abused and neglected
    children and participants in government programs

NSAF Interviewing
  • Screener Interview
  • 5 minutes
  • Sample for households with persons under 65,
    children and low income (below 200 poverty)
  • Over 130,000 completed each round
  • Extended Interview
  • 30-50 minutes
  • Broad substantive content
  • Over 40,000 completed each round

PART 1 Survey Overview
9
Asking About Children
  • Up to two focal children selected in each
    household (ages 0-5, 6-17)
  • Detailed questions on child well-being are asked
    about focal children (not all children in the
    household)
  • Ask Most Knowledgeable Adult (MKA) in the
    household about focal children

PART 1 Survey Overview
10
Asking About Adults
  • MKAs in households with children
  • For households without children, up to two adults
    (ages 18 to 64) randomly selected, who are not
    spouse/partners of each other
  • For households with children, up to two adults
    (ages 18 to 64) without minor dependent children
    in the household randomly selected, who are not
    spouse/partners of each other
  • Ask adult well-being items of respondents and
    spouse/partners

PART 1 Survey Overview
11
Extended Interview Content
  • Household composition, demographics
  • Health status, insurance, access, utilization,
    confidence in getting care
  • Employment, earnings, income, poverty status,
    economic hardship, child support receipt and
    payments
  • Welfare, Food Stamp, other program participation
  • Child care arrangements, social services needs
  • Child and family well-being measures

PART 1 Survey Overview
12
Other Interviewing Features
  • Interviews conducted in English and Spanish
  • Child care section modified for interviewing
    during summer one release group in round 2 held
    for interviewing until June for purpose of
    analyzing child care during summer months.

Survey Weights
  • In general, survey weights
  • Account for sample design
  • Reduce nonresponse biases
  • Adjust for under-coverage
  • Reduce sampling error
  • NSAF weights also
  • Allow for different levels of analysis
  • Enable analysis of important subgroups
  • e.g., school-year sample

PART 1 Survey Overview
17
Steps in NSAF Weighting
  • Account for probabilities of selection
  • e.g. multiple telephones, income subsampling
  • Household and person level nonresponse
    adjustments
  • Population weighting adjustments to control
    totals on demographics such as
  • Age
  • Race/ethnicity
  • Gender
  • Home ownership
  • Education

PART 1 Survey Overview
18
National vs. State Weights
  • Any estimates of the total national population
    should use the National Weight
  • - All White Children vs. All Other Children
  • Any comparison estimates involving state or
    county level data should use the State Weight
  • - State vs. State NY vs. NJ
  • - State vs. National NY vs. USA
  • - County/City vs. State/National NYC vs. NY,
    Brooklyn vs. NYC, Long Island vs. NY

PART 1 Survey Overview
19
Testing Statistical Significance
  • Standard errors produced using standard packages
    will generally be underestimated
  • Standard statistical packages such as SAS, SPSS
    often assume data are from a simple random sample
    in computing standard errors
  • Need to account for features of sample design
    such as unequal probabilities of selection and
    clustering
  • Replicate weights and variance strata/unit
    variables (for Taylor Series linearization) are
    available on the files

Structure of Files without Weights (Round 2)
PART 2 Survey Resources
30
Merging Files
  • For two distinct populations, add the weights
  • combining adult and child data files
  • characteristics of persons under 65 from merged
    files
  • For two overlapping populations, select the
    weight
  • combining adult data files
  • characteristics of adults from merged files
  • OR
  • combining adult and family data files
  • e.g., characteristics of adults with a certain
    number of children in their family, or the number
    of families with some characteristic from the
    adult pair, random adult, or childless adult file

PART 2 Survey Resources
31
Variance Estimation Using Replicate Weights
  • Each set of weights has one full sample weight
    and 60 replicate weights
  • e.g. wgfcad0 wgfcad1 - wgfacd60
  • Replication - subsample from the full sample
  • Use replicate weights provided with data files
    with an appropriate statistical package such as
    Wesvar or SUDAAN
  • Or, do the analysis 60 times
  • e.g. using macros in SAS or STATA

    levels of work effort, and even experiment with a
    state's TANF rules and sanction policies
  • STIC will then compute the family's net income
