German joblessness extended its decline, underscoring the strength of the labor market as Europe’s largest economy seeks to absorb a wave of refugees.

The number of people out of work fell by a seasonally adjusted 16,000 to 2.706 million in April, data from the Federal Labor Agency in Nuremberg showed on Thursday. That’s the seventh consecutive drop, and compares with a median estimate in a Bloomberg survey for no change. The jobless rate stayed at 6.2 percent, the lowest level since German reunification.

The reading signals that German economic growth is strong enough to prompt companies to tap into a pool of potential workers that is rising after the country admitted more than 1 million migrants in 2015. The labor market has been a cornerstone of the nation’s recovery, supporting domestic demand as exports waver in the face of a global slowdown.

The number of people out of work dropped by 7,000 in western Germany and by 9,000 in the eastern part of the country, the report showed.

The outlook could yet deteriorate. Germany’s manufacturing and services sectors cooled slightly in April, leaving the economy in a phase of “unspectacular” growth, Markit said last week after publishing its purchasing managers survey. The Bundesbank sees slowing momentum in the economy this quarter after a strong expansion in the first three months of the year.

Even so, after three consecutive months of decline, German companies are again planning to recruit more staff with recovery seen in manufacturing and services, an employment gauge by the Munich-based Ifo institute showed on Wednesday.
