Estimates are not adjusted for household characteristics but are adjusted using survey weights to obtain nationally representative estimates.
Households were excluded if they were not ‘reliable food reporters,’ that is, did not meet a minimum threshold for food purchases for all quarters in a calendar year.
Since values are calculated using Nielsen’s survey weights, standard errors are presented rather than sd.
Income adjusted for the cost of living is categorised into tertiles for use in regression analysis. In this table, nominal household income and adjusted household income are presented relative to the FPL for ease of comparison.
