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
$84,307 tract average vs. $51,120 citywide (+65%)
The listed tracts average 65% above the citywide median, the page's strongest warning that one municipal figure can hide a sharply different tract picture.
Comparison 3
Monthly rent
$1,331 tract average vs. $1,560 citywide (-15%)
A 15% discount to the citywide median is a material local contrast. Read the individual tract values before treating that gap as typical across the city.
