The US economy posted unexpectedly strong job gains in March, data showed on April 3, 2026, in a development hailed by US President Donald Trump -- but seen with caution by analysts. The world's largest economy gained 178,000 jobs in March, after losing 133,000 in February, and the unemployment rate dropped by 0.1 percentage points to 4.3 percent, the Labor Department said.
