The numbers: The economy added 136,000 new jobs in September, the government said Friday. Economists polled by MarketWatch had forecast a 150,000 increase.

This is the slowest pace of job growth in four months, as businesses grew more cautious about hiring, but employment gains for August and July revised up by a combined 45,000,

And in a separate survey, the U.S. unemployment rate dropped to 3.5%, the lowest rate since December 1969.

One dark spot in the report was that the increase in worker pay over the past 12 months fell to 2.9% from 3.2%. Average hourly earnings were little changed in September following an 11-cent gain in August.

What happened: With manufacturing activity weak, the bulk of the hiring in September was concentrated in the services sector. Education and health care providers filled 40,000 positions.

Government added 22,000 workers in September, but only 1,000 of the jobs were due to federal hiring for the 2020 Census. Economists had expected a much bigger increase in census workers.

Retailers shed 11,000 jobs and manufacturers dropped 2,000 workers.

Stepping back, the pace of job growth has slowed from 223,000 per month in 2018 to 158,000 over the last three months.

Big picture: The resilience seen in the September job report will raise hopes that the economy can avoid a recession. Although manufacturing activity and business investment have been weak, consumer spending has held up well.

Many economists say the employment report is a lagging indicator and they will be watching for readings over the next few months before giving an “all-clear” sign for the economy.

The Federal Reserve has been cutting interest rates this year as insurance against a slowdown in economic growth, but the job report does not add to expectations of another cut in October.

What are they saying? “The job report is a bit of an odd duck. [But] in short, there is a lot of moderation. And the growth in the private sector is already at a pace that is border-line worrisome,” said Robert Brusca, chief economist at FAO Economics.

Fed speakers on Friday said they were generally pleased with the employment report.
