The pursuit of larger samples was motivated by many factors including the challenge of improving sample representativeness and generalizability and the need to obtain larger ns for complex, multivariate analyses. Evidence of this trend was apparent in the progression of studies that were published on social development from the 1970s to the present.

Gains in sample sizes were accompanied by a movement toward sample diversification. Whereas Caucasian samples predominated in published studies during the early decades of this era, this convention eventually was supplanted by ongoing efforts to increase sample representativeness, validate findings in understudied populations, and ensure that underrepresented groups or strata (e.g., minorities, girls and women, low‐income families) were included in scientific research.
