A study by the Yankelovich Center for Social Science Research at the University of California San Diego demonstrated the impact of partisan politics on the economic well-being of Latinos in the United States.

In the TelevisaUnivision survey, Latinos were asked how they get information about candidates and what influences their voting decisions in elections. Party loyalty, with 50% influence, lagged other factors such as debates (68%), interviews with candidates (64%) and political news (58%). This suggests that many Latinos do not rely solely on party history or legacy to make their electoral decisions, as pointed out in the Latin Times article.

The study conducted by political scientist Zoltan Hajnal at the Yankelovich Center analyzed employment, poverty and income data over the past 75 years, comparing the effects of Democratic and Republican administrations on the black and Latino population. The results show that under Democratic presidents, blacks and Latinos have made greater economic advances and racial disparities have narrowed, while under Republican administrations, those disparities have widened.

For example, the median income of the black population grew by $36,000 under Democratic presidents, while under Republicans the increase was only $13,000. For Latinos, the income gap between them and non-Hispanic whites has narrowed by an average of $79 a year under Democrats, while it has increased by $600 a year under Republicans. In addition, poverty and child unemployment rates among blacks and Latinos fell during the Democratic years but worsened under the Republicans.

Although data on Latinos is more limited compared to African Americans, the study points to a consistency in the results over the years. In about two-thirds of the years of Democratic administrations, Latinos experienced improvements in income, poverty and unemployment, while under Republican administrations these conditions worsened in half of the years.

The study concludes that the party that holds the presidency has a significant influence on economic well-being and racial disparities in the U.S. Under Democratic administrations, there has been greater progress in reducing inequalities, while under Republicans, these inequalities have grown. However, the study points out that, despite some advances, racial inequality still persists significantly.
