From the Census Bureau report:
Advance estimates of U.S. retail and food services sales for March 2018, adjusted for seasonal variation and holiday and trading-day differences, but not for price changes, were $494.6 billion, an increase of 0.6 percent from the previous month, and 4.5 percent above March 2017. … The January 2018 to February 2018 percent change was unrevised from down 0.1 percent.
This graph shows retail sales since 1992. This is monthly retail sales and food service, seasonally adjusted (total and ex-gasoline).
Retail sales ex-gasoline were up 0.6% in March.
The second graph shows the year-over-year change in retail sales and food service (ex-gasoline) since 1993.
The increase in March was above expectations, however sales in January and February were revised down slightly.
