Government expenditure on R&D in the US for 2023 was $60.25 billion in constant PPP dollars. From 2024 to 2028, forecasted expenditure grows from $60.9 billion to $63.52 billion. This represents a consistent and modest year-on-year growth, with a Compound Annual Growth Rate (CAGR) of approximately 1.1%. Such a steady increase suggests a stable commitment by the government towards research and development, albeit at a moderate pace.

Future trends to watch for include:

Impact of evolving government policies and budget allocations on R&D spending.
Potential shifts in focus towards emerging technologies like AI and renewable energies.
Economic factors influencing federal budget priorities and potential fluctuations in expenditure.
