Full-time employment before the Great Recession averaged 52.1% of the civilian noninstitutional population over a 12-year period through 2008.
In 2017, the average was still 49.3%, meaning relative to the period before the Great Recession, 6.9 million fewer full-time jobs existed than could have, assuming a real jobs recovery to pre-recession conditions.
In May 2018, the actual percentage has risen to 50.1%. The difference between that and full-time at 52.1% is still 5.1 million full-time jobs.
Things are looking better, but we still haven't recovered from the appalling conditions which ensued upon the Great Recession, not by a long shot.
We still live in a shrunken economy.
