Helen E. Teir, 80, a retired Census Bureau statistician who was editor of the annual "Statistical Abstract of the United States" and other reference books, died of lung cancer Oct. 4 at the Hospice of Northern Virginia. A resident of the District off and on for nearly 60 years, she had moved to the Sunrise of Arlington assisted living facility.

Ms. Teir retired 20 years ago as chief of the compendia staff of the statistical reports division.

The staff compiles and publishes the abstract, a wide-ranging national data book covering demographic, economic and governmental topics.

Ms. Tier, who worked for the bureau for 19 years, was a native of Gardner, Mass., and a graduate of Smith College.

She began her Washington career as an economist with the Office of Price Administration. After World War II, she worked for the Food and Agriculture Organization of the United Nations in Washington and Rome.

Her first work for the Census Bureau was in its agriculture division, for which she assembled information in Kansas. She later trained instructors in census taking.

Ms. Teir was a director of her town house condominium section of Capitol Park in Southwest Washington, a member of the Smith College Alumnae Association, a volunteer in the D.C. public libraries and co-editor of the Census Alumni Association newsletter.

Survivors include two brothers.
