Private sector hiring rebounded in September, according to payroll processor ADP, helped by continued strength in fields such as education and health care. Private companies added 90,000 jobs this month, an improvement from the revised 36,000 jobs in August, new data released Wednesday showed. Economists surveyed by Bloomberg expected a gain of 75,000 jobs. Workers also experienced healthy wage growth: base salaries increased 3.2% year over year and gross pay increased 4.7%. Those who changed jobs saw even greater gains. “This is a solid report,” said ADP Chief Economist Nela Richardson. “After a slight three-month slowdown, this is the first reacceleration we have seen since May.” Sectors such as education and healthcare, along with leisure and hospitality, drove the majority of job creation. The education and health services category has long been a leader in job growth, but the addition of 55,000 jobs in September was particularly strong, Richardson said. “Even for the hardcore sector, it’s still positively strong job growth,” he said. Meanwhile, the financial sector lost 16,000 jobs, while business and professional services jobs declined by 11,000. The ADP data, which comes from private companies, is released ahead of data from a broader Labor Department survey of public and private companies on Friday. Economists expect the economy to add 90,000 jobs by that measure. Claire Boston is a senior reporter for Yahoo Finance covering housing, mortgages and home insurance.
