Have the spending and taxes of the U.S. federal government generally had an upward or a downward trend in the last few decades?

Government spending encompasses a wide range of services provided by the federal, state, and local governments. A spending deficit occurs when the federal government spends more money than it receives in taxes in a given year. Alternatively, a spending overflow occurs when the administration receives more money in assessments than it spends in a year. It is stated to have a fair expenditure plan if administration spending and responsibilities are equal.

Looking at spending in nominal dollars over time is misleading since it ignores population growth and true economic growth. After some time, looking at government spending as a percentage of GDP has become a more useful technique for analysis.

In recent decades, the federal government's spending and taxation trends have fluctuated but not significantly.

In recent decades, the size of government expenditure and taxes expressed as a percentage of GDP has been relatively constant, oscillating between around $18$percent and $22$percent , despite the fact that it crossed that threshold in $2009$, only to sink back to that level by $2013$.

National defence spending as a percentage of GDP has been declining since the $1960$s, notwithstanding modest upticks in the $1980$s under President Ronald Reagan and in the aftermath of the terrorist attack on September$11,$ $2001.$

From $1961$until $1997$, the US government continuously ran budget deficits, acquiring assets in the process. From $1998$to $2001$, it experienced spending plan surpluses before returning to deficits.

During the$1970$s, interest instalments on past government purchases were typically $1-2$% of GDP, but in the $1980$s, they jumped to nearly $3$% of GDP and stayed there until the late $1990$s.

From 1998 to $2001$, the legislature was able to recover a portion of its prior borrowing by running surpluses, and by $2012$, the interest payments on historical government borrowing had decreased to $1.4$ percent of GDP, thanks to low credit rates.
