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 the
Northern Triangle region of 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 92,400 in FY2020, and 486,600 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 the Northern Triangle 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 has corresponded with an increase in
recidivism, with repeat encounters accounting for 26.5% of
total encounters in FY2020 and FY2021, compared with an
average of 11.8% in FY2015 through FY2019. Of those
encountered from the Northern Triangle 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.

Socioeconormic Condions
Land ownership and economic power in the Northern
Triangle 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 Northern Triangle. Analysts
expect the working-age populations of all three Northern
Triangle countries 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
