One page a month: how many US medical sales roles employers opened and closed, who posted most, where, what the roles paid and who said so, counted from employers' own careers pages and frozen with that month's datasets.
Every figure is read from employers' own careers pages, never a survey, and each month's report is written from the frozen datasets of that month, so it does not change after it is published except through the corrections page. The datasets themselves, with every row, come with the Business plan; the report is free to read and to cite with credit.
