The International Council of Shopping Centers and Goldman Sachs announced that their joint holiday consumer tracking survey indicates roughly 15 percent of shoppers ages 16 and older – a total of 23 million consumers – plan to shop on the day before Christmas.

“With many last-minute shoppers still needing to finish their gift lists, brick-and-mortar retailers will be buzzing with activity on Christmas Eve,” Michael Kercheval, president of the shopping centers group, said in a news release.

According to the survey, more men (17%) plan to shop that day than women (13%). By age, people 18 to 34 years old are more likely to be shopping (21%) than those 55 and over (8%).

By region, 19% of those living in the Midwest said they were planning on doing last-minute holiday shopping on Christmas Eve, while those in the West (16%), Northeast (13%) and South (13%) were relatively less likely to shop that day.   

On the day after Christmas, 19% of consumers reported they were likely to shop, with men (18%) and women (19%) about equally inclined to do so.

After-Christmas shopping is also expected to be relatively busy, according to the survey, with 47% of consumers planning to shop sometime during the workweek between Christmas and New Year's Day.
