“Remember, there was no public data of apartment prices, and in the vacuum of no numbers, I supplied a number, and they wanted to do a story on the bad market, and I put a label on it, how bad it was, right?”

The claim, plainly

At the time the Corcoran Report was created, there was no publicly available data on New York City apartment prices.

a quote alone can be ambiguous, so this restates it with the references and context of the conversation around it resolved. AI-written; the tape below the player is the source.

Assessment

Historical real estate records confirm that when Barbara Corcoran first published the Corcoran Report in mid-1981, there was no public database, government registry, or published aggregate market report tracking New York City apartment prices. In 1981, owner-occupied apartments in Manhattan were overwhelmingly cooperatives (co-ops), which were legally classified as personal property and exempt from public recording until New York State legislation mandated their disclosure via ACRIS in 2006. In addition, third-party market reports and indices (such as Miller Samuel/Douglas Elliman and REBNY reports) did not exist until the 1990s.

Co-op apartment sales in NYC were treated as private transactions and were exempt from public recording until New York State passed legislation closing the loophole in 2006.
Prior to the Corcoran Report's initial release in 1981, there were no centralized public databases, government registries, or published market reports tracking NYC apartment sale prices.
Other recognized market reports, such as those from Miller Samuel / Douglas Elliman and the Real Estate Board of New York (REBNY), were not initiated until the 1990s or later.
