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
Home value
$183,911 tract average vs. $154,600 citywide (+19%)
A 19% 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
Monthly rent
$975 tract average vs. $1,063 citywide (-8%)
The tract average runs 8% below the citywide median. That modest difference shows why the tract table can refine a city-level starting point.
