Changes in two important location factors, markets and labor, are investigated for convergence and their relationship to the regional growth of manufacturing. Analysis of the spatial composition of labor suggests that the Manufacturing Belt has experienced skilled-labor-augmenting technical progress to a greater extent than other regions, especially the Southeast. Though wage rates continue to diverge in the Manufacturing Belt, biased technical change and improvement in markets may help the region maintain a residual hegemony. However, the central states may also compete, possibly forming a new manufacturing belt in the U.S.
