WASHINGTON (AP) — Activity in the U.S. services sector, where most Americans work, slowed slightly in April after hitting an all-time high in March.

The Institute for Supply Management said its monthly survey of service industries showed a drop to a still high reading of 62.7%, 1 percentage point lower than the record high of 63.7 set in March.

Any reading above 50 indicates the sector is expanding. The April level marks the 11th straight month of expansion in the services sector after a two-month contraction in April and May last year when the country was struggling with widespread shutdowns caused by the coronavirus pandemic.

The reading on service industries followed an ISM report Monday that activity in manufacturing also slowed in April to a level of 60.7%. The manufacturing slowdown was attributed to widespread supply chain shortages.
