Since 1980, the Centers for Disease Control and Prevention's spending has increased 1,094.9%, while overall spending has increased 193.7%.

As a percentage of the overall federal budget, a positive number means agency net spending made up some positive share of total federal spending; a negative number means that net generated funds offset a portion of total spending. CDC spending grew more than overall federal spending since 1980, which means that its share of the federal budget increased. In 2024, CDC accounted for 0.2% of overall federal spending.

Major legislation, internal or global economic conditions, and acute events like the COVID-19 pandemic can affect spending year to year. For example, the federal budget fluctuated during the pandemic, rising from $5.3 trillion (in 2023 dollars) in 2019 to $7.7 trillion in 2020 and $7.8 trillion in 2021.
