Respondents' concern over effects of illegal immigrants
Gallup, Inc., The Gallup Poll [Online]. Available: http://www.gallup.com/poll/
127649/Americans-Value-Aspects-Immigration-Reform.aspx [June 16, 2010].
Table adapted by SOURCEBOOK staff.
Overall, the survey respondents indicate substantive concerns with the presence of illegal immigrants in the U.S. Three items relate to the overall question: (1) Unfair burden on U.S. schools, hospitals, and government; (2) Encourages other immigrants to move here illegally; (3) Low wages earned by illegal immigrants reduces overall wages paid to American workers. The overarching question is how concerned respondents are for each of the items, and the highest ranking item was related to the unfair burden immigrants place on schools, hospitals, and government. For all three items, there is significant difference in the percentage of responses under very concerned vs. under somewhat concerned. A majority of U.S. citizens are very concerned about the impact of illegal immigrants on budgets for U.S. services, U.S. jobs, and attractiveness of U.S. To further illegal immigrants.
The data source is from primary research conducted by the Gallup Poll. Just over a thousand randomly selected people were interviewed over the phone, which, as Gallup indicates is adequate for assessing effects. The refusals and don't know responses were not included in the data. The data are weighted using statistical procedures to reduce the impact of possible sampling bias. Weighting of data improves the validity of the results since it reduces the threat of contamination of data due to bias or non-representative samples. In addition, a split sample technique is used to measure the impact of different working in the questions. Split sample technique improves reliability.

The Global Terrorism Database II (GTD2) project is intended to provide a basis...
The barriers to compilation have been restricted public availability of terrorism data, and "insufficient temporal and spatial coverage of available data." The researchers set out to code and verify data that was previously unavailable from a data set covering world terrorism activity from 1998 through 2004. The data set is sufficiently robust as to permit methodologically derived insights into the phenomenon of terrorism and counter-terrorism.
A unique attribute of the data set is that the researchers have not classified the data into categories by definitions of terrorism. Rather, they leave that to users of the data set through the application of filters -- which can be described for others who may wish to replicate as study -- and coding that meets the researcher's definitions of terrorism. This is an elegant solution that permits analysis of data based on changes made to the definitions used, and provides a "work-around" for the theoretical issues that have surrounded study of the terrorism phenomenon.
