Not significantly. Humans are made up of matter already available at the earth's surface, so population increase alone effects neither the amount nor distribution of the earth's mass.

Technological civilization might at some point meaningfully shift the distribution of mass, but I don't think it has up to this point.

“Humans are responsible for some of the wobble in Earth's spin.

Since 1899, the Earth's axis of spin has shifted about 34 feet (10.5 meters). Now, research quantifies the reasons why and finds that a third is due to melting ice and rising sea levels, particularly in Greenland—placing the blame on the doorstep of anthropogenic climate change.”
