What does the size of the Venus of Willendorf suggest about the people that made her?

They were nomads.

Explanation:

The Venus of Willendorf, a small limestone statuette, has more than 25,000 years of existence. From the data of the time, it is believed that those who made it were nomads: people who in groups of between 15 and 25 men used to stay in these camps for several months a year, especially in winter, undertaking from there 'expeditions' to search materials, collect fruits and engage in hunting.
