US Black Friday: more shoppers but less spent per head

More than 154 million people made purchases during the four-day retail extravaganza that began Thursday on Thanksgiving, compared to 151 million last year, the National Retail Federation said.

Shoppers spent an average of $289.19, compared to $299.60 in 2015.

Sales over the Thanksgiving holiday, which extends into so-called Cyber Monday, are a good indicator of the health of US consumer spending.

Online sales dominated. A total of 44 percent of those who took part in the NRF survey said they had bought via the internet while 40 percent went to a brick-and-mortar store.

"It was a strong weekend for retailers, but an even better weekend for consumers, who took advantage of some really incredible deals," NRF president Matthew Shay said.

The most popular day to shop online was Black Friday itself, the day after the Thanksgiving holiday. Of those who purchased online over the four-day period, 74 percent did so on Friday, up 1.3 percent from last year.

And of the people who went to actual stores over this shopping period, 75 percent did so on Black Friday, up 3.4 percent from last year, the NRF said.

Millennials, aged 18-34, drove the increase in shopping, with eight out of ten buying something over the long weekend.

Around 56 percent of smartphone owners and 53 percent of tablet owners used these devices to assist with their shopping.
