inequality geographically. there are places like kentucky, west virginia, central appalachia, the coal regions where life expectancy is going down. the mississippi delta, other pockets around the country, and this is part of a story we've been tracking for a long time now, which is kinda, what's happening to this country, the working class, rural america? what's happening that's driving down health outcomes, and what we're seeing in this report is this rising inequality. it's great if you're in fairfax or falls church, or arlington or bethesda. but a lot of places in this country, people are going the wrong direction, and that's what we've been writing about. >> and joel, you mentioned fairfax county, i know it's significantly lower, the death rate than the national average. other than maybe that we should all be moving out to tyson's or springfield, what exactly does that mean? >> so what it really is, is

map of income, access to health care, access to quality health care, ask then thinnd things th about all the time. the rate of obesity, are you a smoker, how much exercise do you get in your leisure hours? and so people of a higher socio-economic status often have better access to health care, they often are not smokers. so this is all stuff, we know it's common sense cal in a way. i was struck, what really struck me was new york city, brooklyn, much better life expectancy, and some remote places in alaska also saw improvements. it's kind of hard to tease out what's driving each of these factors. how much of it is people moving in or out of areas. but the authors of the report from the university of washington tried to factor in migration, tried t

by age group, and this is part of a lot of research going on these days in terms of death rates. and the big picture is, why is the u.s. not doing better? particularly given how much money we spend? >> yeah, clearly a disparity there. thank you, joel, that's fascinating stuff. >> thank you. draining the park. what's going on inside the white house that's forcing people out of a popular park? plus, the mystery captivating the nation's attention. two doctors, engaged to be married,
