The number of available U.S. jobs rose in October to the second-highest level in 14 years, and companies kept hiring at a healthy pace, adding to evidence of an improving economy.

Job openings increased 3.2 percent to 4.83 million, the Labor Department said Tuesday. That's just below August's total, which was the highest on records dating back to 2000.

Total hiring slipped 0.4 percent to 5.1 million after reaching a seven-year high in September. The number of people quitting was mostly unchanged at a six-year high of 2.7 million.

The overall figures paint a picture of a more dynamic job market, with businesses filling more open jobs and more Americans quitting, typically for better-paying opportunities. More quits and more job postings provide more opportunities for the unemployed to find work.

Job openings have been rising strongly all year, but total hiring has only picked up in the past couple of months. That suggests employers are stepping up their efforts to fill open positions.

More people quitting and growth in hiring can also help up drive up wages, which have barely kept up with inflation since the recession ended.

The data comes after last Friday's surprisingly strong jobs report. Employers added a net total of 321,000 jobs in November, the most in nearly three years. Job gains have averaged 241,000 jobs a month this year, the healthiest pace in 15 years.

Still, the job market is not yet back to full health. There are still nearly 7 million people working part-time jobs who would prefer full-time work, up from 4.1 million before the Great Recession.

Tuesday's data is from the Job Openings and Labor Turnover survey, or JOLTS, which provides a more detailed look at the job market than the monthly employment report. It includes figures for overall hiring, as well as the number of quits and layoffs. The monthly jobs figures are a net total of job gains or losses.

Federal Reserve Chair Janet Yellen has cited the levels of quits and hires as key indicators of job market health. She and other Fed officials are monitoring those trends as they consider when to raise short-term interest rates from near-zero levels. Most economists forecast that won't happen until the middle of next year.
