When Democrats Win, Blacks, Latinos, and Whites Win

With Donald Trump and the Republican Party making major gains among Latino voters, racial and ethnic minorities are once again front and center in debates about the future of the Democratic and Republican parties. With half of Latinos voting for Trump and a growing share of the White working class favoring Republican candidates, many wonder if the Republican Party will dominate elections in the years to come. On the other side, many Democrats are wondering how to woo and re-engage minority voters. 

Which party really has the better case to make? One way to gain some insight into the future is to look at the past. Specifically, how well have racial and ethnic minorities and Whites done economically under Republican presidents and how does that compare to changes in their economic well-being under Democratic presidents. Using data from the U.S. Census to track annual changes in income, poverty, and unemployment over more than five decades, I looked to see how each of America’s major ethnic groups has fared under Democratic or Republican presidents. The findings are striking. When Republicans are in the White House, minorities generally lose ground. But Democratic presidents have presided over steady and substantial improvements for communities of color – and the nation as a whole.

Trends in Income, Poverty, and Unemployment

Economic outcomes clearly diverge under Democratic versus Republican presidents – especially for African Americans.

• Under Democratic presidents, Black families’ incomes grew on average $1005 dollars annually, but grew only by $335 dollars under Republicans. The Black unemployment rate fell by a net 8.5 percentage points across the 22 years of Democratic leadership, but went up by a net of 3.6 points during 29 years of Republican presidencies. Across the years of Democratic leadership, Black child poverty declined by a net of 43.9 percentage points, but grew slightly when Republicans held the White House.
• Although data on Latinos and Asian Americans do not go back as far in time, the results are similar. For Latinos, Democratic presidencies are associated with large annual gains in income, substantial declines in poverty, and real drops in unemployment, while under Republican administrations Latinos tend to experience few gains in income, become poorer, and experience greater unemployment. Latino incomes grew an average of $800 annually under Democrats, but grew by an average of $100 annually under Republicans. Less consistent data for Asian Americans also suggest gains under Democrats versus stagnation under Republicans.

Tellingly, White Americans make gains under Democrats, too. On average, under Democratic administrations, White incomes have grown, and White joblessness and poverty have declined.

Could the Trends be Coincidental?

Like all social scientists, we probed our data to see if the racial and ethnic trends might be explained away by other factors. Perhaps Democratic presidents have gotten lucky and presided over expanding economies, while Republican leaders have happened to win office in depressed times. Three different sets of analyses suggest that this is not the case:

• Partisan differences persist after one takes into account the overall state of the economy or other longer-term trends in U.S. well-being. Controlling for inflation and changes in the gross national product, and considering other factors like oil prices and the proportion of adults in the work force, we find similarly large gains for minorities under Democrats and equally sharp losses under Republicans.
• The partisan trends are remarkably consistent over many years. Black incomes grew in 70% of the years that Democrats held the presidency; Black poverty declined in 77% of those years; and Black unemployment fell in 73% of those years. In sharp contrast, Blacks more often than not lost under Republican administrations.
• The longer Democratic administrations are in office, the more they appear to be able to help African Americans and other minorities experience economic gains, while the longer Republican administrations hold office, the more the fortunes of these groups suffer. Even White Americans do better economically under Democrats than they do under Republicans, once either party has been in power for four years or more.

It is not just that Democrats inherit good economies and Republicans are bequeathed bad economies. Everything points to a real and substantial partisan divergence.

Why Do Democrats Do More to Boost Incomes and Reduce Poverty?

Many policy differences between Democrats and Republicans can help to explain minority gains under Democrats.

• Policies intended to boost the incomes and employment of poor or lower-income Americans could certainly play a role. Examples range from President Lyndon Johnson’s War on Poverty to President Bill Clinton’s expansion of the earned income tax credit (which gives low income working people a tax refund check).
• Racially targeted efforts like the Civil Rights Act or more recent initiatives to expand affirmative action in government hiring can also buoy minority economic fortunes, as can a range of policies that disproportionately impact minority communities, such as education efforts and immigration reforms.
• Any policy that encourages overall economic and job growth can make a positive difference for minorities – along with everyone else. Democratic presidents tend to place more emphasis on such overall economic growth, while Republicans often stress reducing inflation, even if unemployment ticks up as a result.

Going forward from 2024, Republicans are likely to intensify their efforts to woo minority voters – often by stressing that they will be better stewards of the national economy than Democrats. But voters should look to see which party actually delivers. The relationship between minority well-being and party control is so consistent and so substantial that Democrats clearly have the more plausible case to make. Their policies have done more to help minorities and Whites alike. Given that most U.S. children are now born to minority parents, it will become all the more true with every passing year that economic gains for minorities also make the economy stronger for all Americans. When it comes to boosting incomes and reducing poverty and joblessness, we all stand to rise and fall together.
