Summary
Increased border enforcement significantly reduces Mexican immigrant populations in U.S. states. More Border Patrol officers lead to a substantial decrease in immigrant shares, particularly in border states like California and Texas.
Area of Science:
- Economics
- Sociology
- Public Policy
Background:
- Understanding the spatial distribution of immigrants is crucial for policy-making.
- Previous research has not fully established the causal impact of border enforcement on immigrant settlement patterns.
Purpose of the Study:
- To provide the first evidence on the causal effect of border enforcement on the spatial distribution of Mexican immigrants in the U.S.
- To quantify the impact of increased border security personnel on immigrant settlement.
Main Methods:
- Employed an instrumental variables strategy to address endogeneity.
- Utilized administrative delays in budgetary allocations for border security as an instrumental variable.
Main Results:
- An increase of 1,000 Border Patrol officers in a U.S. state decreases its share of Mexican immigrants by 21.9%.
- Without changes in border enforcement from 1994-2011, California and Texas would have had 8 percentage points higher shares of Mexican immigrants.
Conclusions:
- Border enforcement is a significant determinant of Mexican immigrant spatial distribution.
- Increased border security leads to a reallocation of immigrants away from states with higher enforcement levels.

00:53Migration
9.1K
Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.

01:25Selected Data About Geographic Locations
325
Geographic Information Systems (GIS) rely on two core types of data: spatial data and attribute data.Spatial DataSpatial data defines the physical location of features within a coordinate system, typically expressed in terms of latitude and longitude. It provides precise positioning for elements like roads, rivers, or buildings.Attribute DataAttribute data complements spatial data by adding descriptive information about these features. For example, a road's spatial data includes its start and...

Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

01:21Chemotaxis and Direction of Cell Migration
6.2K
Cells can detect chemical cues in their environment and reorganize the cytoskeleton to migrate toward them or away from them. This directional migration, called chemotaxis, is essential during embryogenesis and development, immune response, tissue repair and regeneration, and reproduction. These chemical cues can either attract or repel the cell's movement. For example, axon development is determined by a combination of chemoattractants and chemorepellents that direct the growing axon...

The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.
