More than half the 800,000 Puerto Rican migrants living in the United States resided in New York City in 1970. Mortality statistics from 1969-1971 indicate that Puerto Rican natives in the metropolis have a standardized mortality ratio for cancer which is 77% of that of non-Puerto Rican white males and 81% of that of non-Puerto Rican white females. The age-adjusted death rates of the Puerto Rican-born residing in New York City for cancers of the lung, prostate, bladder, ovary, and rectum are low, ranging from 43-70% of those of non-Puerto Rican whites; rates for breast cancer and colon cancer are somewhat lower relative to those for non-Puerto Rican whites. As is true for Puerto Ricans on the island, migrants to New York City have excessive levels of cancer of the cervix and esophagus (each roughly three times that of non-Puerto Rican whites) and cancer of the stomach (almost twice that of non-Puerto Rican whites).
1970年，居住在美国的80万波多黎各移民中，超过半数居住在纽约市。1969年至1971年的死亡率统计数据表明，在这座大都市里，波多黎各本地人的癌症标准化死亡率，是非波多黎各白人男性的77%，是非波多黎各白人女性的81%。居住在纽约市的波多黎各出生者，其肺癌、前列腺癌、膀胱癌、卵巢癌和直肠癌的年龄调整死亡率较低，为非波多黎各白人的43%至70%；乳腺癌和结肠癌的死亡率相对于非波多黎各白人略低。和岛上的波多黎各人一样，移民到纽约市的人宫颈癌和食管癌发病率过高（每种癌症的发病率约为非波多黎各白人的三倍），胃癌发病率过高（几乎是非波多黎各白人的两倍）。
