More than 8,000 same-sex couples have married in New York City in the year since the state legalized gay marriage, generating $259 million for the city’s economy, city officials said on Tuesday.

Same-sex couples account for about 10 percent of the marriage licenses issued by the city since last July, when the state lifted a prohibition on same-sex marriages.

The change has brought $16 million in direct revenue, and considerably more in overall economic impact. A total of 235,000 hotel room nights were booked at an average daily room rate of $275, the city said in a statement.
