Appendix 6A

SPM/PPM Threshold Components—Availability in the CE Interview Survey/Taken from Other Sources

ComponentSource
REQUIRED FOR CURRENT SPM
CONSUMER UNIT (CU) COMPOSITIONRequired to obtain estimation sample
Presence of adults and childrenCE estimation sample includes all CUs with children
BASIC BUNDLE (FCSUti)FCSUti estimated at 83% of the 47th–53rd percentiles of expenditures for basic bundle for reference CU, then S + U estimated separately by housing tenure (rent, own without a mortgage, own with a mortgage); replaces the SU component in FCSUti
Food purchased with money incomeCE includes food at home and away from home
Food obtained with in-kind benefitsCE used for SNAP; BLS imputes WIC and the National School Lunch Program
ClothingCE
Shelter (including obtained with subsidies)CE used for housing tenure, rent, mortgage payment, property taxes, property insurance, maintenance; BLS imputes rental assistance
Utilities (including obtained with subsidies)CE, BLS imputes Low Income Home Energy Assistance Program [LIHEAP]
TelephoneCE
InternetCE
MULTIPLIER1.2 times basic bundle to account for other necessary expenditures (e.g., nonwork-related transportation, personal care, household supplies)
ADJUSTMENTSEquivalence scale applied based on number of adults and children; housing component (by tenure) adjusted geographically by the ratio of 5-year ACS tabulations of median rent and utilities for 2-bedroom units with complete kitchen and plumbing facilities in a state or metropolitan area to the U.S. median.
FINAL THRESHOLDSBasic bundle + multiplier, adjusted for family composition and geographic shelter cost differences (see “Adjustments”)

ComponentSource
REQUIRED FOR PANEL’S RECOMMENDED PPM
CONSUMER UNIT COMPOSITIONSee above
REVISED BASIC BUNDLE (FCti)FCti estimated at 83% of 47th–53rd percentiles of expenditures for revised basic bundle for reference consumer unit
FoodCE used (see above re: imputation of in-kind food benefits)
ClothingCE
TelephoneCE
InternetCE
MULTIPLIERThe current 1.2 multiplier will need to be updated to reflect the revised basic bundle accounting for other necessary expenditures
ADJUSTMENTEquivalence scale applied based on number of adults and children
NEW/REVISED THRESHOLD COMPONENTSTaken from other sources (see below) and added to revised basic bundle threshold
HEALTH INSURANCESum of health insurance needs for health insurance units in CU (e.g., parents and children one unit, grandparent a second unit): for people under 65 and over 64 but not on Medicare, need is benchmark ACA plan—second-lowest-cost Silver plan in the health insurance Marketplace in an individual’s geographic area; for Medicare recipients, need is full cost of least expensive Medicare Advantage plan with prescription drugs (premium subsidies added to resources; premium and other MOOP costs subtracted up to MOOP cap in benchmark plan)
HOUSING (including utilities)HUD FMRs (includes utilities) for applicable number of adults and children (based on number of bedrooms) for applicable metropolitan area/nonmetropolitan county (housing subsidies added to resources for renters; implicit rent net of expenses added to resources for owners)
FINAL THRESHOLDSFor applicable CU composition/location, revised basic bundle + multiplier + health insurance + housing/utilities
FUTURE ADDITION—CHILDCAREThe PPM extends childcare out-of-pocket costs that are subtracted from resources to parents who are in school or disabled; in a future revision, the panel recommends that childcare needs be added to the thresholds in a similar manner to health insurance and childcare subsidies be added to resources
