NYC DOF FY2027 Final Assessment Roll

Value Concentration

NYC property value is held very unevenly across its 1,167,962 tax lots. Just 5.3% of lots — the highest-value ones — account for half of the city's total market value.

The concentration curve

Also called a Lorenz curve — the further this line bows above the diagonal, the more concentrated NYC property value is among fewer lots

Headline numbers

The top 100 highest-value tax lots alone hold 6.9% of all NYC property market value ($132,074,886,514).
The top 1,000 lots hold 16.5% ($315,346,487,538).
The top 10,000 lots — well under 1% of all lots citywide — hold 33.7% ($644,819,058,275).
The top 50,000 lots hold 47.8% ($914,266,749,671).
2,821 lots are individually worth — together they hold roughly 23.5% of citywide value.

See which entity owners hold the most of that value

Concentration among the largest lots is closely tied to housing scale, too — see how it plays out in unit-size distribution on the Housing page, where a small number of very large buildings hold a disproportionate share of residential units.
