That document doesn’t seem to compare things to national rates, but to my knowledge the NYC life expectancy is above NY state’s, which itself is significantly above the national average. The densest parts of Manhattan, which also have some of the most air pollution (but high incomes) have the highest life expectancies.
With a brief googling it looks like cancer incidence is in line with national averages, but mortality is lower. Significant racial and socioeconomic disparities impact both averages.
