ACAsignups.net has some news on enrollment for January 2014:
A total of 3,299,492 had enrolled in Obamacare plans as of Feb. 1, according to HHS.
Damn. I was off by 0.017%. :)
More importantly the age mix is starting to normalize as younger adults are entering the risk pool.
In January, 27 percent of those who selected plans in the Federally-facilitated Marketplace are between the ages of 18 and 34, a three percentage point increase over the figure reported for the previous three month period. Young adult enrollment grew by 65 percent in January, from 489,460 at the end of December to 807,515 as of Feb. 1, while all other age groups combined grew by 55 percent.
81 percent of young adults ages 18 to 34 selected plans at the Silver metal level or higher (Silver, Gold and Platinum plans).
The Massachusetts experience was that younger and healthier people waited. The age distribution got younger each month the deadline got closer. And shockingly, a program that is a a kissing cousin of the Massachusetts program design is experiencing similar growth patterns.
