and enrico moretti is professor of economics at the unversity of california, berkeley and author of "the new geography of jobs," which examines how and why hiring is stronger in some u.s. cities than in others. lisa lynch, let me start with you. looking first at the overall number of job gains this was better than expected, right? >> absolutely. we saw strong growth in the economy in terms of jobs, and across a variety of sectors. and economists had been forecasting much slower numbers given what we had seen in the prior three months of pretty weak job growth and information that we had about the growth in the overall economy, the gdp growth being pretty weak in the last three, the prior three months to this employment report. >> brown: now lisa, at the same time, the rate inched up in spite of that hiring. explain that to us. >> well, it was interesting. we learned a little bit of math today. the unemployment rate was reported as going up from 8.2% to 8.3%. but when you actually dig into the numbers, the unemployment rate went from 8.22% to 8.25 percent. and then the bls just rounded

. >> brown: and enrico moretti, what do you see in today's numbers or in recent numbers as we talk about a glass half full or glass half empty, what's going on? >> the labor market is improving but too slowly. we need 150,000 new job each month just to absorb the young people in training the labor force sochlts's not surprising that today's numbers in terms of unemployment were not particularly good. the labor force participation rate which is the fraction of adults with a job is the lowest it has been in 20 years. the current pace is going to take 8 to 10 years to go back to where we used to be six years ago. so it is half full but also half empty. >> brown: so you praise both short and long term thinking here. i know when you talk about the geography of jobs, where the jobs are, you look long and short term. think short term for a little bit for us first. what does your work tell us about where the jobs are and where they're not. >> well, we think of the u.s. economy as one economy. but the reality is that there are 320 different economies. one for each metropolitan area in the country
