Lawrence Greksa

Lawrence P. Greksa, Ph.D. (Penn State, 1980), is a human population biologist who utilizes evolutionary and ecological paradigms to examine the biological and cultural adaptations of humans to a variety of stressors. His most recent work has focused on the Old Order Amish, particularly the demographic impact (fertility, out-migration rates, rates of joining the church) of the sociocultural changes associated with the thus far successful attempt of the Amish to maintain their cultural integrity while at the same time adapting to changing economic conditions which have required them to have much higher levels of contact with the surrounding modernized society.

About the site

Amish Studies is an academic website developed by the Young Center for Anabaptist and Pietist Studies at Elizabethtown College to provide reliable information on Amish life and culture.

Designed to assist scholars, students and the general public, the site was developed with support from the National Endowment for the Humanities as part of a collaborative research grant on Amish diversity and identity in the 20th century. The research team included principal investigator Donald B. Kraybill of Elizabethtown College (Pa.) and two co-investigators, Steven M. Nolt of Goshen College (Ind.) and Karen M. Johnson-Weiner of SUNY Potsdam (New York).

The Amish population statistics are updated annually in the summer. Other information will be revised and added on a periodic basis.
