Measuring Poverty in the U.S.

  • Current Official Poverty Measure

– First adopted in 1965 – Now under Office of Management and Budget (OMB) Statistical Policy Directive No. 14. – Poverty thresholds updated each year by change in Consumer Price Index (CPI) – Compares before-tax money income to thresholds – Uses Current Population Survey (CPS ASEC)

  • Does not account for

– Provision of near-money benefits – Necessary expenses (taxes, health care, work) – Higher standards and levels of living since 1965 – Geographic price differences among regions

Supplemental Poverty Measure (SPM)

  • Observations from the Interagency Technical Working Group -

March 2, 2010

  • Will not replace the official poverty measure
  • Will not be used for resource allocation or program eligibility
  • Census Bureau and BLS responsible for improving and updating

the measure

  • October 2011 Report with detailed estimates
  • Based on NAS panel on measuring poverty 1995

recommendations

Comparing the Official measure and SPM Threshold Concept

Official Measure

  • Cost of minimum food diet for a

two adult/two child family in 1963 times three to cover all other expenses

Supplemental Measure

  • Expenditures over the most recent

5 years on food, clothing, and shelter (including utilities and all mortgage expenses) (FCSU) from the Consumer Expenditure Surveys

– 33rd percentile – all family units with exactly 2 children (adjusted, when needed, to be equivalent to 2 adult/2 child family unit) – plus 20 percent to cover all other expenses.

SLIDE 6

Threshold Adjustments: by shelter type

Official

  • No adjustments

Supplemental

  • Adjust by distinguishing

differences in shelter expenditures by renters,

  • wners with a mortgage,

and owners without a mortgage

6

slide-7
SLIDE 7

Threshold Adjustments: family size and composition

Official

  • Separately developed

thresholds by family type; lower thresholds for elderly singles and couples Supplemental

  • Reference family

threshold adjusted by use

  • f a three parameter

equivalence scale, which assumes children need less than adults and economies of scale for larger families

7

slide-8
SLIDE 8

Economic Unit of Analysis

Official

  • Families or unrelated

individuals Supplemental

  • All related individuals who

live at the same address, any co-resident unrelated children who are cared for by the family (such as foster children), and any co-habitors and their relatives

8

slide-9
SLIDE 9

Threshold Adjustments: by geographic area

Official

  • No adjustments

Supplemental

  • Adjust for housing cost

differences using five years of ACS data on rental costs

  • Make adjustments by

MSA and non-MSAs in each state

  • Continue to research

inter-area price indices

Family Resource Definition

Official

  • Gross (before-tax) money

income from all sources

Supplemental

Gross money income:

  • PLUS value of near-money federal in-

kind benefits for FCSU (e.g., SNAP, housing subsidies) and tax credits (EITC).

  • MINUS income and payroll taxes and
  • ther nondiscretionary expenses

– child care, work-related expenses; – child support payments; –

  • ut-of-pocket medical care

expenses, including health insurance premiums)

10

slide-11
SLIDE 11

Nondiscretionary Expenses

Payroll and state and federal income taxes

  • Use current methods,

incorporate new CPS ASEC questions Child care and other work related expenses

  • Use data from new CPS ASEC

questions on child care expenses paid

Medical Out of Pocket Expenditures (MOOP)

  • Use data from new CPS ASEC

questions

  • investigate the pros and cons
  • f making an adjustment for

the uninsured Child Support Paid

  • Use data from new CPS ASEC

questions to subtract child support paid from income

SLIDE 12

Supplemental Poverty Measure (SPM) differs from Census experimental measures

  • Separate thresholds for homeowners with mortgage, homeowners

without a mortgage and renters

  • Estimation sample for thresholds – families with two children rather

than two adult/two child families at 33rd percentile of FCSU

  • Use the new CPS ASEC questions to adjust income

– Child support paid – Child care paid – Medical out of pocket expenditures

  • Geographic adjustments based on ACS and using specific

metropolitan areas

  • New method for valuing housing subsidies

Third Poverty Measure

  • Relative poverty measure (OECD)
  • Unit of analysis = household
  • Equivalence scale = square root of household size
  • Disposable income = Y - t
  • Threshold = 50% of median equivalised household
