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

Recent Trends
According to a model developed by academics at the
University of Texas at Austin, an estimated 311,000 people,
on average, left the Northern Triangle region of Central
America (see Figure 1) annually from FY2014 to FY2020,
with the majority bound for the United States. Flows have
varied from year to year, with an estimated 709,000 people
leaving the region in FY2019 and an estimated 139,000
people leaving the region in FY2020. Surveys conducted in
2020 found many potential migrants in the region 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 FY2021, U.S. Border Patrol encountered nearly 684,000
foreign nationals from the Northern Triangle at the U.S.
Southwest border, including 309,000 Hondurans, 279,000
Guatemalans, and 96,000 Salvadorans (see Figure 2). The
Border Patrol apprehended 287,000 of those individuals
under Title 8 of the U.S. Code (immigration) and expelled
nearly 397,000 under Title 42 of the U.S. Code (public
health). Taken together, individuals from the Northern
Triangle accounted for 41% of all Border Patrol encounters
at the Southwest border, outnumbering Mexican nationals,
who accounted for 37% of the total. Of those encountered
from the Northern Triangle, about 17% were
unaccompanied children, 39% were traveling with family
members, and 45% 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.

Socioeconoic Conditions
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 and facilitated
the diversification of the region's once predominantly
agricultural economies, those 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 increase over the next two
decades, since approximately 45% of Guatemalans, 42% of
Hondurans, and 36% of Salvadorans are under the age of
20. Without improved job creation, new workers may be
forced to choose between pursuing limited, precarious
employment opportunities in the unregulated informal
sector and 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
rural communities have experienced declining employment
opportunities in the coffee sector, which typically provides
a crucial source of seasonal income for about 1.3 million
