Huh? The Rosslyn-Ballston corridor has census tracts in the 40k-50k people per square mile range and that will only increase with what is being built there. So does Silver Spring Md. In 20 years, all metro lines will be like that. Have you seen what is being built around the DC metro station. Almost all growth will be funneled to metro stations by law here in the region. That's how Arlington Va got that way.

40-50K where
they range between 7 and 20K (max) and within less 1/2 a mile drop sometimes below 3K
Places like Reston today are averaging in the areas closer to the Silver line are closer to 3-6K and drop below that just outside; even if based on your link they add the 30K by 2050 (that was the long range plan based on your link earlier) they would be on average like 10-12K at a small peak - that gives way to less dense very quickly in 40 years
edit : my bad I did find a 52K and 44K ppsm that has about 5K people living in them and represent .2 sq miles combined; the area averages far closer to 8-11K and drops off really fast to 4K or less - they were the outliers - and represent .1% of the metro population.
Now again I think the plan and development is good but the numbers and sheer densities you discuss are outliers as best and don't portray any large portion of the area - that is my issue - not the development itself but how you describe it incorrectly

ever been to South Philly or Queens?
they both achieve these level with rowhouse neighborhoods (South Philly has very few high rises) - with higher concentrations than Ballston or Rosslyn for sure - though most is closer to 30K including my neighborhood in Bella Vista and these are rowhouse neighborhoods in fact there may not be better examples of rowhouse neighborhoods in the country to be honest - but maybe you will one 6 story building somewhere and call it a high rise neighborhood I supoose

We will see how much of an outlier those are in the 2020 census. I will leave it at that.
So would you consider L.A. to be a more centralized metro than Chicago?
No, but DTLA is more centrally located within its region. The Chicago Loop is on a lakefront.

either way is an impressive number, but just loosely adding add up job centers without those it appeared the 1.6 number was way high with them it seemed spot on - I think they are actually included actually based on some quick math
Ok. I could see how Century City and Burbank sneak in that way. Still not sure about Westwood--the geographic heart is a good 13 miles from DTLA. Regardless, it's a boatload of jobs and humanity. I would love to do a job count of just Central LA and the Westside.
highly varied from <3k to 20-30K depending on the suburb probably will not change much between now and 2020
Remind me which Philadelphia suburbs have densities of 20-30K? That's average SF city limits density...probably average Philly city limits density over much of the city. It's pretty undisputable that overall, CA suburbs are the most dense on average. SF's suburbs range from 5K (mostly around the Valley and in to Santa Clara County where San Jose is) to 11,000 ppsm (Berkeley) to 13,000 ppsm (Daly City) down to 3,200 ppsm (Walnut Creek way out in the East Bay). Having family in the Philly burbs, I find it very very hard to comprehend that they are any denser than the most dense suburban cities of the Bay Area, which don't really top 13,000 ppsm and rarely exceed 10,000 ppsm. Camden, NJ is less than 9,000 ppsm and is probably the most dense Philly suburb I can think of (it is essentially right across the river).
NYC has a lot of dense suburbs, but overall in its expansive MSA land area definitions, has a ton of super low density suburbs, as well (very typical for most of the country, especially the NE). The only 3 metro areas that actually maintain high density by American standards are the Bay Area, Los Angeles, and New York.
