US Labor Force Participation Rate mostly held flat from last month which has been the trend for several months now.
As the big baby-boomer generation retires (a group that's bigger than those who are currently entering the labour force), the overall rate goes down. If for example 4 million 65 year olds are retiring each year, and only 3 million youngsters are entering the labour force - it will decline by 1 Mio. each year due to demographics.
Sigh. We seems to re-ligate this every time unemployment numbers come out. Yes, you are right about the generational trends. But one easy way to account for that is to look at Labor Force Participation Rate by age bracket, especially working age bracket.
Jan 2000 Jan 2009 Mid 2013 Mid 2014
Age 25-34 84.5% 81.4% 81.3% 80.8%
Age 35-44 85,1% 84.0% 82.6% 82.3%
Age 45-54 82.9% 82.0% 80.1% 79.8%
We are in worse shape in terms of labor participation now than a year ago and significantly worse than Jan 2009 let alone Jan 2000.
