Using moving-industry data to depict U.S. migration patterns.

"Migration analysis is hindered by the lack of up-to-date migration data. This paper examines the feasibility of using information from the American Moving Conference (AMC), the trade organization of the moving industry, to develop timely estimates of gross in- and out-migration and net migration rates at the state level. When adjusted for the spatially varying size of migrant households and the spatially varying market share of the professional moving industry, the number of AMC inbound and outbound shipments provides useful, but slightly imperfect, estimates of migration in 1990 and 1991. Viewed as a time series, adjusted AMC shipment data accurately reveal the major migration stories of the last decade. AMC-based estimates for 1992, 1993, and 1994 provide a picture of state in- and out-migration for years in which official data are not yet available."

Short-term dynamics of the U.S. interstate migration system, 1980-1988.

"This paper identifies short-term fluctuations in the [U.S.] interstate migration system using annual state-to-state migration flow data from Internal Revenue Service (IRS) records for the period, 1980 to 1988. Measures of migration efficiency are employed to indicate the net redistribution of population between states relative to the size of underlying gross interstate flows. Three findings stand out: (1) migration was more effective in redistributing the population in years of economic retrenchment than during periods of growth and expansion, (2) the dominant pattern of population redistribution shifted from a core-periphery configuration evident in the 1970s and early 1980s to a bi-coastal distribution by the mid-1980s, and (3) the most dramatic event of the 1980s was the oil glut and decline in oil prices and profits which ravaged the economies of energy states in the West South Central and Mountain regions....Overall, results demonstrate the high degree of temporal and spatial volatility in the U.S. interstate migration system."

Determinants of black interstate migration, 1965-70 and 1975-80.

"This paper presents and tests a regression-based model of black interstate migration. Explanatory variables include characteristics of origins and destinations, distance, and two migrant stock measures. The model is tested using black interstate migration flows published by the U.S. Bureau of the Census for 1965-70 and 1975-80." The emphasis is on the determinants of black migration, particularly for the period 1975-1980.
