Immigration and political division

Despite the majority of the population having immigrant roots, the topic of immigration in the U.S. remains one of the country’s longest-standing political debates. Support among Republicans for restrictive immigration has grown alongside Democratic support for open immigration. This growing divide has deepened the polarization between the two major political parties, stifling constructive dialogue and impeding meaningful reform efforts and as a result, has led to dissatisfaction from all sides. In addition to general immigration policy, feelings toward illegal immigration in the U.S. also vary widely. For some, it's seen as a significant threat to national security, cultural identity, and economic stability. This perspective often aligns with support for stringent measures like Trump's proposed border wall and increased enforcement efforts. On the other hand, there are those who are more sympathetic toward undocumented immigrants, as demonstrated by support for the Deferred Action for Childhood Arrivals (DACA) program.

In 2022, the greatest number of illegal aliens returned in the United States were from the Philippines, with ****** illegal aliens returned. India, Canada, China, and Russia rounded out the top five in that year.

The 2019 Yearbook of Immigration Statistics is a compendium of tables that provide data on foreign nationals who are granted lawful permanent residence (i.e., immigrants who receive a “green card”), admitted as temporary nonimmigrants, granted asylum or refugee status, or are naturalized. The Yearbook also presents data on immigration enforcement actions, including apprehensions and arrests, removals, and returns.

This is a .csv file containing an export obtained from the Altmetric Explorer containing metadata including links and altmetrics of 1,095 articles with the keyword 'immigrants’ mentioned at least once in the sources tracked by Altmetric in the past 1 year. This is the result of a 'dumb search' for the keyword "immigrants" in all articles mentioned across all sources tracked by Altmetric during the past 1 year. Therefore data in the dataset will require manual refining depending on your interests. (For example the term can be used in relation to animals, not humans). The dataset is also likely to require deduplication. This dataset is shared as the British Prime Minister David Cameron has been reported warning that "illegal immigrants would be removed from the UK". This dataset is shared as a .csv file as a means to offer a bibliographic collection of academic/scientific articles including the keyword "immigrants" and to have a fixed data point documenting the articles with the keyword 'immigrants' tracked by Altmetric and their metrics as of 30 July 2015 at around 9:30 AM BST. The links and metrics included in the dataset were correct at the time of exporting the report. Metrics are expected to change in reports obtained at later dates. Hopefully the sharing of this dataset can encourage research into which of these articles about immigration are available open access and which ones are not, as well as the tracking of future changes in their metrics. With gratitude to Altmetric for enabling access to the data.

The aim of the Transatlantic Trends Survey is to identify the attitudes of the public in the United States and European countries towards foreign policy issues and transatlantic issues. Transatlantic Trends: Immigration, a special topic public opinion survey conducted yearly since 2008, is a project of the German Marshall Fund of the United States. For 2011, the Immigration survey examined attitudes and policy preferences related to immigration in France, Germany, Italy, the United Kingdom, and the United States. This collection focused on respondent perceptions of legal and illegal immigrants, conditions for admittance of immigrants, level of support for policies to reduce immigration, preconditions for citizenship, and whether or not immigration enriched society. Respondents were asked to identify the most important issues facing their country, to evaluate their government's performance in managing immigration and the economy, whether immigration presented a national opportunity or a problem, and whether they believed immigrants were integrating well into society. Additional topics included the developments in North Africa and the Middle East, responsibility for displaced refugees coming from North Africa, and whether the respondent's nation should offer economic aid to countries committed to democracy. Lastly, respondents were asked about which political party they identified with, their voting intentions in the next national election, and whether political party agendas would influence their vote. Demographic and other background information includes gender, age, stage at which full-time education was completed, age when stopped full-time education, employment status, ethnic background, country of birth, citizenship, parents' citizenship status, type of phone line, ownership of a mobile phone, and the number of people in their household.

Demographic and other background information includes age, gender, ethnicity, citizenship, origin of birth (personal and parental), religious affiliation, age when stopped full-time education and stage at which full-time education was completed, occupation, type of locality, region of residence, and language of interview.
