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
Monthly rent
$968 tract average vs. $1,097 citywide (-12%)
The tract average runs 12% below the citywide median. That modest difference shows why the tract table can refine a city-level starting point.
Comparison 3
Home value
$319,400 tract average vs. $328,700 citywide (-3%)
The listed-tract figure sits within 3% of the citywide median. Treat this as broad agreement, not proof that every block has the same conditions.
