Page 3 carries the assortment pair: stockkeeping units in the produce department were 173 in 1987 and 335 in 1997, a 94-percent increase, per Litwak 1988 and 1998 — a commercial period-survey proxy relayed by a federal bulletin. The facts are Tier C; federal republication does not make the underlying trade survey official microdata. The same sentence pair carries the floor-area contrast (4,817 to 5,140 square feet, under seven percent) that shows the assortment densifying into nearly the same space. A stockkeeping unit is a distinct shelf item — one commodity in one form, package or brand — not a commodity; do not read these counts against the FADS commodity variety, which measures a different thing. The remembered '~100 items in 1980 rising to ~400 by 1997' pair that circulates is wrong on both ends and both years and appears nowhere in this document.

Where this source appears

2 records across 2 decades and countries. Documented gaps are included; a source cited for a gap does not establish a value.

0 of 2 records have a current source audit. A transcription check reads a declared numeric field from a pinned local source file; a calculation replay reads its operands and applies the declared method and rounding rule. A source audit does not independently validate the source or every claim in a record. The date is the last successful local audit; the build checks that its bindings still match.
