Durand was born, in 1871, in Romeo, Michigan. When he was still a child, however, his parents moved to a homestead in South Dakota. Durand attended Yankton College for one year before transferring to Oberlin College. He received a Ph.D. from Cornell University in 1896. After receiving his doctorate, Durand moved between several government and academic positions until 1909, when he became deputy commissioner of corporations. Later that year, President Taft appointed him the new director of the census. He replaced Samuel North, who had left after repeated clashes with the secretary of commerce and labor, and took over the Census Bureau well into the planning process for the 1910 census.

Durand concentrated much of his energy on improving the preparation of census reports. He pioneered several lasting innovations in the presentation of data at the Census Bureau. For example, Durand introduced the publication of state-level reports and the early release in press releases of statistics for which there was the greatest demand (such as the total population of individual cities, states, and the United States population). These releases were be followed by bulletins, abstracts, and final reports with greater detail.

After leaving the Census Bureau in 1913, Durand eventually took a place on the U.S. Tariff Commission, where he served from 1935 until his retirement in 1952. He died in 1960.
