But with Adams threatening to use executive order to end NYC’s sanctuary city status, one concern is that the DOC or NYPD will honor more of ICE’s detainers. And could coincide with an increase in the number of detainers issued by ICE under Trump.

For context, there were around 412,000 undocumented migrants living in NYC in 2022, according to the latest numbers by the Mayor's Office of Immigrant Affairs.

The number of detainers from ICE to DOC dropped to a third during the first full year under Biden compared to Trump’s last full year. Now, the numbers are creeping bac up: 347 detainers were issued to DOC between July 1, 2023 and June 30, 2024 datawrapper.dwcdn.net/IPiYE/3/

Since October 1, 2016, NYPD has not transferred anyone to ICE.

But the DOC has. Between July 2017 and June 2024, DOC transferred 124 individuals to ICE. All but one person had a conviction for a serious or violent crime.

But this is where NYC’s sanctuary status comes into play. NYC does not honor these detainers, unless the person is convicted — not simply charged — with a serious or violent offense (felony). The person could also show up on a terrorist watch list. There must also be a judicial warrant out for hem.

Quick definition break: A detainer is a hold on someone in the custody of another state or law enforcement agency, sorta like putting a hold on a library book while someone else has the book checked out. And it is civil, not criminal, because living in the U.S. without documents is not a crime.

The number of detainers from ICE to NYPD remained high under Trump’s administration, then plummeted under Biden’s administration to a low of just 57 detainers this past year, from July 2023 to June 2024.
January 16, 2025 at 3:39 PM
The number of civil immigration detainers from ICE to the NYPD jumped 13 times --- from 80 to 1023 --- once Trump got into office in 2016, as compared to the last year of Obama’s presidency. datawrapper.dwcdn.net/yY6Yu/5/

NYC’s Hispanic population data shows a similar pattern from 2010 to 2020, growing by by 154,000 over the decade, with most of the growth in the Bronx followed by Queens. This data is collected by the U.S. Census & NYC’s Department of City Planning. storymaps.arcgis.com/stories/46a9...

The Bronx’s percent of Spanish speakers grew between 2012 and 2022 by a shy 0.38 percentage points. But the other boroughs dropped by half a percent (Queens & Staten Island), two percent (Manhattan) or a full two and a half percentage points (Brooklyn). datawrapper.dwcdn.net/J7Zxt/1/

I wondered how this had changed in the prior 10 years. The same pattern holds in 2012: the Bronx has the highest percentage of residents who speak Spanish at home (46%), followed by Queens (24%), Manhattan (23%), Brooklyn (17%) and Staten Island (11%). datawrapper.dwcdn.net/1u2ZT/1/

Yet, the Bronx is only the fourth most populated borough with 1,343,839 residents. It trails behind Brooklyn (2,496,494), Queens (2,223,983) and Manhattan (1,571,876).
January 6, 2025 at 2:19 AM
Queens ranked second in terms of percent of Spanish speakers, 23 percent, and Manhattan next with 21 percent. Then Brooklyn with 15 percent and Staten Island with 10 percent.

That's according to the 2022 American Community Survey put out by the U.S. Census Bureau.
