Where the tract view differs from the citywide view
How these gaps are calculated
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.
Comparison 2
Household income
$108,753 tract average vs. $85,364 citywide (+27%)
A 27% 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.
Comparison 3
Home value
$788,788 tract average vs. $982,600 citywide (-20%)
A 20% discount to the citywide median is a material local contrast. Read the individual tract values before treating that gap as typical across the city.
