“Do Immigrants Make Us Safer?” asked the title of a New York Times Magazine article (Press, 2006). The article reported findings from several U.S.-based studies, including several conducted by Harvard sociologist Robert Sampson in Chicago. For each of the following findings, draw the table of cells that would comprise the research design. Include the labels for each row and column. 

a. Mexican immigrants were more likely to be married (versus single) than either blacks or whites. 

b. People living in immigrant neighborhoods were 15% less likely than were people living in nonimmigrant neighborhoods to commit crimes. This finding was true among both those living in households headed by a married couple and those living in households not headed by a married couple. 

c. The crime rate was higher among second-generation than among first-generation immigrants; moreover, the crime rate was higher among third-generation than among second-generation immigrants.
