Recent Caseload Statistics for U.S. District
Courts: Criminal Defendants Charged by
Type of Offense
September 26, 2023
The Administrative Office of U.S. Courts regularly compiles data related to the workload of the federal
courts. This Insight provides an overview and analysis of data related to one measure of workload—the
number and percentage of criminal defendants charged with various types of offenses in U.S. district
courts. Specifically, it provides information about (1) the percentage of defendants charged with certain
types of offenses in U.S. district courts for the period 2001-2022; (2) the combined percentage of
defendants, during this same period, charged with the three most common types of offenses—
immigration, drugs (excluding marijuana), and firearms/explosives; and (3) the three most common types
of offenses for which defendants were charged in each U.S. district court in 2022.
The data below include defendants charged with felonies or Class A misdemeanors (or, if the defendant
was charged with a petty offense, the case was assigned to a district court judge rather than a magistrate
judge). Additionally, the data exclude defendants transferred among district courts and do not include
defendants charged in U.S. territorial district courts. This Insight does not provide legal analysis of the
offenses discussed.
Percentage of Defendants Charged by Type of Offense (2001-2022)
Nationally, during the 2001-2022 period, immigration-related offenses were the most common for which
defendants were charged during 13 (59%) of the 22 years. And as shown by Figure 1, since 2008 (with
the exceptions of 2020 and 2021), immigration has been the most common type of offense for which
defendants have been charged. The percentage of federal defendants charged with immigration-related
offenses ranged from a low of 14.2% in 2001 to a high of 34.8% in 2019.
Examples of specific immigration-related offenses include (1) improper reentry by an alien after having
been removed from the United States; (2) the smuggling of aliens into the United States, including
arranging transportation or otherwise assisting unauthorized individuals to enter or remain in the United
States; and (3) fraud and misuse of visas or other documents. For additional information about statistics
regarding immigration-related offenses, see.

Drug-related offenses (excluding marijuana) were the most common offenses for which defendants were
charged in 9 (41%) of the 22 years during this period, including a 7-year streak from 2001 to 2007. The
percentage of defendants charged with drug-related offenses ranged from a low of 22.0% in 2010 to a
high of 28.7% in 2020.
Examples of specific drug-related offenses include (1) selling, distributing, or dispensing of controlled
substances or regulated chemicals; (2) manufacturing such substances and chemicals; and (3) possession
of such substances and chemicals.
The third most common type of offense for which defendants were charged are those related to firearms
and explosives. The percentage of defendants charged with such offenses ranged from a low of 8.4% in
2010 to a high of 16.1% in 2020 (and has consistently been above 10.0% since 2015).
Examples of specific offenses related to firearms and explosives include (1) possession of a firearm or
ammunition by prohibited persons; (2) the use, carrying, or possession of a firearm in furtherance of a
drug felony or a federal crime of violence; and (3) to knowingly possess or manufacture certain types of
firearms or other devices.
Most recently, for 2022, 28.4% of all federal defendants were charged with an immigration-related
offense, 27.0% were charged with a drug-related offense (excluding marijuana), and 15.7% were charged
with an offense related to firearms and explosives.

Combined Percentage of Defendants Charged by Type of Offense (2001-2022)
As shown by Figure 2, defendants charged for offenses related to immigration, drugs (excluding
marijuana), or firearms/explosives represented, in combination, an increasing percentage of all defendants
charged in U.S. district courts during the 2001-2022 period.
In 2001, the combined percentage of defendants charged with at least one of these types of offenses was
49.9%—representing nearly half of all defendants charged with a federal offense. In contrast, that
percentage has been above 70.0% since 2018 (reaching a high point of 73.4% in 2019).

Most Common Offenses Charged by U.S. District Court (2022)
There is variation in the percentage of defendants charged with different types of offenses across the 91
U.S. district courts.
While defendants charged with immigration-related offenses represented a plurality (28.4%) of all
defendants charged nationally in 2022, such charges, as shown by Figure 3, represented the greatest
percentage of defendants charged in relatively few U.S. district courts in 2022—specifically, 4 (4.4%) of
91. Each of the four district courts is located in the West or South.
In 67 (73.6%) of 91 U.S. district courts, the most common type of offense for which defendants were
charged was drug-related (excluding marijuana)—including each of the 14 district courts located in the
Northeast and 14 of 17 district courts located in the West.
Offenses related to firearms and explosives were the most common offenses for which defendants were
charged in 16 (17.6%) of 91 U.S. district courts. Of the 16 courts, 12 (75.0%) are located in the South,
while the other four courts (25.0%) are located in the Midwest.
For three U.S. district courts, the most common type of offense for which defendants were charged was
not one of the three types discussed above—these exceptions were the U.S. district courts for the District
of Columbia (regulatory offenses), South Dakota (sex offenses), and Wyoming (violent offenses,
including robberies and assaults).
