Early life and education
Ocasio-Cortez was born in the Bronx, New York City.[7] Her mother Blanca Ocasio-Cortez is from Puerto Rico and her late father Sergio Ocasio was also a native of the Bronx.[8][9] Until the age of five, she lived with her family in an apartment in the planned community of Parkchester, the Bronx.[9] Ocasio-Cortez credits her early experience seeing the treatment of her cousin by law enforcement, as well as her Catholic faith, as being part of her desire to see an overhaul of the mass incarceration within the criminal justice system.[10]
