Private sector firms added 44,000 jobs in July compared to expectations of 75,000 forecast by economists polled by Dow Jones. The weaker private sector hiring gains in July represent the lowest monthly tally of the year, according to ADP data. Education and health services sectors led the monthly rise, adding 36,000 positions last month, followed by 10,000 job gains in the financial activities sector. Though job growth typically rises at restaurants and hotels over the summer months, that sector only posted 2,000 job gains in June, ADP previously reported. BLS is due to release official government estimates of July hiring gains on Friday, including an updated unemployment rate.
