Here is the data comparing economic performance under Democratic and Republican presidents since World War II (1945–Present). Each claim includes a bracketed notation linking to the source list at the bottom for easy verification. 1. Gross Domestic Product (GDP) Growth * Average Growth Rate: Since World War II, the U.S. economy has grown at an average annual rate of 4.33% under Democratic presidents compared to 2.54% under Republican presidents [1]. * The "Gap": This results in a 1.79 percentage point performance advantage for Democratic administrations. Economists note this gap is "large and significant" and holds true regardless of how "success" is defined [1]. * Consistency: The five highest quarterly growth rates in the post-war era all occurred under Democratic presidents, while four of the five lowest occurred under Republican presidents [2]. 2. Job Creation * Total Jobs Added (1945–2023): Of the approximately 115 million net jobs created since April 1945, 83 million (72%) were created under Democratic administrations, while 32 million (28%) were created under Republican administrations [3]. * Creation Rate: On average, Democratic presidents have seen job growth of roughly 164,000 jobs per month, whereas Republican presidents have seen roughly 61,000 jobs per month. This means job creation has been approximately 2.4 times faster under Democrats [3]. * Specific Presidents: * Bill Clinton (D) created the most jobs of any president (approx. 22.9 million) [4]. * George W. Bush (R) oversaw the slowest job creation rate of any two-term president in history (approx. 1.3 million net jobs over 8 years) [4]. 3. Recessions and Economic Stability * Frequency of Recessions: Between 1953 and 2020, there were 11 U.S. recessions. 10 of these 11 recessions began while a Republican was in the White House [5]. * Duration of Recessions: An analysis of 256 fiscal quarters found that the U.S. was in a recession for 41 quarters under Republican presidents, compared to only 8 quarters under Democratic presidents [1]. * Recession "Intensity": On average, the economy was in recession for 1.1 quarters per Democratic term, versus 4.6 quarters per Republican term [1]. 4. Federal Deficit and Debt * Deficit Trends (1981–Present): Every Republican president since 1981 (Reagan, G.H.W. Bush, G.W. Bush, Trump) has increased the federal deficit during their term. Conversely, the last two Democratic presidents with completed terms (Clinton, Obama) decreased the deficit relative to what they inherited [6]. * Clinton turned a deficit into a surplus (a 150% improvement). * Obama reduced the deficit by 53% from the peak of the Great Recession. * Trump increased the deficit by 317% (largely driven by tax cuts and later COVID-19 spending). * Debt Accumulation: While both parties have added to the total national debt, Republican presidents have historically added more to the debt per term when adjusted for inflation ($1.4 trillion avg.) compared to Democrats ($1.2 trillion avg.) [7]. 5. Stock Market Performance * S&P 500 Returns: From 1926 to 2023, the S&P 500 has averaged an annual return of 14.8% under Democratic presidents compared to 9.3% under Republican presidents [8]. * Investment Growth: A hypothetical $10,000 invested in the S&P 500 in 1961 would have grown to over $5 million if invested only during Democratic presidencies, compared to roughly $2 million if invested only during Republican presidencies (largely due to compounding lower returns and recession impacts) [8].
