The challenge to cut Chicago's 30-year life expectancy gap in half by 2030

ABC 7 CHICAGO (WLS) -- Your ZIP code determines your lifespan, according to researchers. Experts told the I-Team inequality is a cause of death and can kill people well before the average life expectancy of 78 in the U.S.

The difference between living downtown compared to some neighborhoods on the South and West Sides can be up to 30 years, according to recent analysis done at New York University School of Medicine. That's the largest gap in the country.

The City Health Dashboard and the CIA World Factbook reveal Streeterville's life expectancy of 90 is slightly higher than Monaco, the highest for any country in the world. Nine miles south, Englewood's 60-year life expectancy matches the Republic of the Congo, a third world country.
