WASHINGTON (AFP) - US consumer spending ticked up 0.6 percent in January after six months of decline, driven by a surge in retail sales, seasonally adjusted government data showed Monday. The Commerce Department's headline number beat analysts' consensus forecast of a 0.4pc gain. In December, consumer spending fell 1.0 percent from the prior month, and over the June-December period the spending - which accounts for two-thirds of US economic activity - fell 3.5pc. On an annual basis, consumer spending in Jan was 1.6pc lower.
