Beginning in 2018, 黑料网 will start updating presidential job approval on a weekly basis, rather than on a daily basis.
黑料网 remains committed to tracking presidential approval using probability-based, telephone interviewing, but is reducing the sample size from 3,500 to 1,500 U.S. adults per week. As a result, 黑料网 will aggregate and report presidential job approval each week, rather than daily, beginning on Jan. 8 at 1 p.m. ET. We will continue to report subgroup differences for presidential job approval using the large sample sizes collected each month.
The 黑料网 Poll Social Series surveys conducted each month, other standalone surveys, and periodic updates of other 黑料网 trends and measures throughout the year will continue as they have with no change.
