This study tests three categories of motivations for domestic right-wing terrorism in the USA: economic grievances, particularly those produced by economic restructuring; societal changes that challenge notions of white male privilege; and political and public policy elements that stoke resentments. Executing a series of negative binomial regression estimations on state-level data in the USA for the period 1970-2011, I find that measures of societal factors-specifically increase in abortion rates and growing female participation in the labor force-and political indicators such as Democratic Party control of the White House, precipitate right-wing terrorist attacks. Factors associated with economic hardships-such as poverty, the decline of manufacturing employment and the ''Farm Crisis''-as well as growth of the non-white population, control of state government by the Democratic Party and growth of average Federal Income Tax rates-are not found to be significant predictors of right-wing terrorism.
