Paper Finding: Given the setting that our data is drawn from, we expect that these results could be even more pronounced in a context such as the United States, where tuition fees are high.
News Context: The researchers also found that the relative probability of second-borns studying arts programs was 27 percent higher than for first-borns, while the difference was 36 percent between third-borns and first-borns.

Paper Context: Since the Swedish education system provides free tertiary education, these results are not driven by the exhaustion of family financial resources by earlier-born siblings. Given the setting that our data is drawn from, we expect that these results could be even more pronounced in a context such as the United States, where tuition fees are high. We also found clear differences in the birth order patterns by socioeconomic status, as the effects were substantially stronger amongst siblings from high-SES families than amongst siblings from low-SES families.
