Robert Martin Groves (born September 27, 1948)[1] is an American sociologist and expert in survey methodology who has served as the interim president of Georgetown University in Washington, D.C., since November 2024.

[6] When Groves was an associate director at the United States Census Bureau in the early 1990s, he argued that potentially millions of minorities who typically voted Democratic were being undercounted.

[9] During his confirmation hearings, Republican senators raised concerns based on Groves' previous actions that he would apply statistical adjustments to populations believed to be undercounted, thereby inflating their numbers and affecting the apportionment of congressional seats.

However, senators Richard Shelby and David Vitter continued to delay his confirmation due to lingering worries regarding statistical adjustments.

They also sought assurance from the Obama administration that the controversial community group ACORN would not be involved in grassroots outreach related to the 2010 Census.
