The consumer price index, a key barometer of what consumers pay for goods and services, rose four percent last month from a year earlier, the Labor Department said Tuesday.
Compared with March, the consumer price index (CPI) rose 0.1 percent.
Core CPI, which excludes food and energy prices, was up 5.3 percent on a 12-month basis. Compared with a month earlier, core prices were up 0.4 percent.
The figures were largely in line with expectations. Economists had forecast 4.1 percent for headline inflation and 5.3 percent for core.
