Private sector hiring picked up meaningfully in September, according to payroll processor ADP, adding 90,000 jobs and comfortably beating the 75,000 economists surveyed by Bloomberg had expected. The gain also marks a sharp improvement from a revised 36,000 jobs added in August. ADP’s chief economist described it as a genuinely strong report, noting it represents the first reacceleration in hiring since May, following a three-month slowdown.
