These comparisons use the average of the tract medians listed on this page and the ACS citywide median. They are two different geographic summaries, so the gap is a reading aid rather than an estimate of a typical household.
$89,987 tract average vs. $72,357 citywide (+24%)
A 24% premium over the citywide median makes this one of the clearer local contrasts on the page. The row-level values show whether it is broad or driven by a few tracts.
$1,155 tract average vs. $1,063 citywide (+9%)
The tract average runs 9% above the citywide median, a modest separation worth checking against the individual rows before drawing a local conclusion.
$246,030 tract average vs. $244,400 citywide (+1%)
The listed-tract figure sits within 1% of the citywide median. Treat this as broad agreement, not proof that every block has the same conditions.
