Using the databases of more than 700 million current and historical job postings, Burning Glass Technologies looked at the percentage of job postings that required a background check going back to 2012 to determine the likelihood of employers to demand screenings in job postings. Across all occupations, the percentage dropped from 8.7% in 2012 to 7.9% in 2017. The peak demand was in 2014. The study has revealed that the biggest drops have been in lower-skill jobs. It is equally important to note that the positions seeing drops in background check requests are not those where checks are required by law.
