(Bloomberg View) -- President Donald Trump talks a lot aboutbringing manufacturing jobs back to America.

Judging from the latest employment data, he should be moreconcerned about department-store workers and the cable guy.

Overall, the jobs report for July showed employers still verymuch in hiring mode.

They added an estimated 209,000 jobs, bringing the three-monthaverage to 195,000 -- more than enough to provide work for agrowing population.

The unemployment rate declined slightly to 4.3 percent,suggesting that the economy is running at close to fullcapacity.

Yet down at the level of individual sectors, there are alwayspockets of vulnerability as global competition and technological innovation render some jobsobsolete or unnecessary.

This is the kind of disruptive change that can sideline workersor require them to make difficult adjustments, creating a sense ofunease even as the broader job market performs well.

So where are the biggest areas of vulnerability?

To approach an answer, I divided the economy into about 350small sectors -- ranging from boat building to insurance claimsadjusting.

I then ranked them by the number of jobs lost from June 2016through June 2017 (the most recent month for which this level ofdetail is available). Here are the top 10 (click chart toenlarge):

Manufacturing sectors -- the kind Trump featured last monthduring Made in America Week -- are completely absent.

It's hard for makers and metal-bashers to dominate job losses(or gains) as they have in the past, because they just don’t employthat many people anymore.

All told, goods-producing industries employ 20 million people,compared with more than 100 million for private serviceproviders.

The biggest job losers were mostly in retail, prolonging a trendthat most likely reflects the migration of customers to theinternet.

Department stores, which employ about 1.3 million people,eliminated 24,000 jobs, followed by electronics stores with about21,000.

Separately, wired telecommunications carriers lost almost25,000, probably thanks to cable-cutting and the gradual demise ofthe landline.

Among services subsectors that shed jobs, total losses amountedto almost 340,000, compared with just 92,500 for goodsproducers.

Although changing vocations might be easier for a sales clerkthan for a coal miner, that's still a lot of people who have tofind somewhere to go.

As Bloomberg View has noted, the advent of artificialintelligence could bring a lot more disruption to servicesindustries in coming decades.

If Trump and his successors want to keep Americans in jobs,they'll have to do more to help the country's workforce meet thechallenge.
