Central American Migration: Root Causes and U.S. Policy


U.S. policy toward Central America has been a subject of
significant debate and oversight over the past decade as
Congress has sought to address the underlying factors
driving migration from the region to the United States.

Recent Trends
According to a model developed at the University of Texas
at Austin, an estimated 377,000 people, on average, left
Northern Central America (see Figure 1) annually from
FY2018  to FY2021, with the majority bound for the United
States. Flows have varied from year to year, with an
estimated 651,000 people leaving the region in FY2019,
followed by 92,000 in FY2020, and 487,000 in FY2021.
Surveys conducted in 2020 found many potential migrants
had postponed their plans in the midst of the Coronavirus
Disease 2019 (COVID-19) pandemic but intended to
undertake their journeys once governments lifted cross-
border travel restrictions.

In FY2022, U.S. Border Patrol encountered nearly 521,000
foreign nationals from Northern Central America at the
U.S. Southwest border, including 199,000 Hondurans,
228,000 Guatemalans, and 93,000 Salvadorans (see Figure
2). The Border Patrol apprehended 177,000 of those
individuals under Title 8 of the U.S. Code (immigration)
and expelled nearly 344,000 under Title 42 of the U.S.
Code (public health). According to U.S. Customs and
Border Protection, the use of Title 42 corresponded with an
increase in recidivism, with repeat encounters accounting
for 26.5% of total encounters in FY2020 and FY2021, up
from an average of 11.8% in FY2015-FY2019. Of those
encountered from Northern Central America in FY2022,
about 22% were unaccompanied minors, 24% were
traveling with family members, and 54% were single adults.

Root   Causes
Although motives vary by individual, difficult
socioeconomic and security conditions-exacerbated by


natural disasters and poor governance-appear to be the
most important drivers of this mixed flow of economic
migrants and asylum-seekers. Research suggests such flows
can become self-reinforcing over time, as families seek
reunification and those who leave their communities serve
as examples for, and share their experiences and resources
with, those who remain behind.

 Socioeconomic  Conditions
 Land ownership and economic power in Northern Central
 America historically have been concentrated in the hands of
 a small group of elites, leaving a legacy of extreme
 inequality and widespread poverty. Although market-
 oriented economic reforms in the 1980s and 1990s
produced greater macroeconomic stability, moderate
economic gains have not translated into improved living
conditions for many in the region. Analysts expect
working-age populations in Northern Central America will
continue to grow over the next two decades, since
approximately 44% of Guatemalans, 40% of Hondurans,
and 35% of Salvadorans are under the age of 20. Without
improved job creation, new workers may have to choose
between pursuing limited, precarious employment
opportunities in the unregulated informal sector or seeking
opportunity elsewhere.

Natural  Disasters
Environmental shocks have aggravated the already difficult
living conditions in the region. Some scientific studies
indicate that Central America has become significantly
hotter and dryer in recent decades, and portions of the
region have struggled with a series of prolonged droughts
since 2014. In addition to facing repeated crop losses, some
