WASHINGTON — A strikingly improving labor market, coupled with broad economic growth and a falling federal budget deficit, is improving the prospects of bipartisan cooperation next year — if Republicans and Democrats can seize on easing fiscal pressures to give both sides some of their wish lists.

On Friday, the Labor Department reported that United States payrolls rose by 321,000 jobs in November and that hourly wages jumped, easily beating economists’ expectations. This year will be the best for job creation since the boom years of the late 1990s.

But that good news is only the latest in a recent string. Health care spending is growing at the slowest pace since statisticians began tracking it in 1960. The number of uninsured Americans has fallen 30 percent in a year. At an average of $2.71 a gallon, regular unleaded gasoline is at its lowest price since 2010 and is still dropping, according to AAA. Economic growth between July and September was revised upward last month to 3.9 percent.

And the budget deficit, already below its 40-year average as measured against the economy, is likely to fall again this fiscal year, according to the Congressional Budget Office, which said on Friday that tax receipts in the first two months of the new fiscal year were 6 percent higher than a year ago, while spending was up only 2 percent. The budget office has already estimated the deficit for the current fiscal year would be 2.6 percent of the gross domestic product, down from 2.8 percent recorded in the fiscal year that ended Sept. 30. But that projection was delivered in August, before the spate of economic optimism.
