Another good employment report today suggested that the labor market is continuing to improve. Employer payrolls increased by 227,000 in February and by an average of 245,000 over the last three months. The private sector again led the way with 233,000 new jobs and has now experienced two consecutive years of job growth. Although the unemployment rate was unchanged, new entrants to the labor market expanded the labor force and the overall share of the population working edged up.
