This research note documents the Hispanization of the poor in Los Angeles (California). The single most dramatic change in income inequality in this city over the last few decades is the ethnic recomposition of the economically disadvantaged. The number of poor Latinos has grown so significantly since the late 1960s that this group now constitutes a majority of the poor in this region. The paper is organized into three parts. Part I, "Poverty in Los Angeles," summarizes the basic trends in poverty based on unpublished data. Part II, "Low-Income Workers and Poverty," indicates that Hispanic poverty is not primarily a problem of leaving the job market but one of inadequate income from work. Part III, "Some Underlying Factors," discusses the following five conditions that have contributed to the growth of the Hispanic poor: (1) the massive influx of immigrants who have few marketable skills; (2) inequalities in educational opportunity and underpreparation for the job market affecting American-born Hispanics; (3) discrimination in the labor market; (4) a decline in better-paying industrial jobs; and (5) greater job competition among Latinos due to the increasing supply of Hispanic labor. The paper includes a list of 16 references and 14 notes include statistical data and calculations. (AF)
