@Anon168463 -I understand that the population is significantly higher than this, but I think that the data used in the article is based on the 2000 Census data.
I think that many Americans have government jobs. As a matter of fact, more people are employed by the public sector than work in the private sector. This is a first in the United States as the growth in government jobs has expand and the unemployment numbers for those in the private sector has increased dramatically.
I also think that the field of information technology employs a lot of people and has been a constant source of new jobs since 2000. Lately, Social Media jobs have been on the rise and people with this expertise are in demand in America.
