The document discusses dating and mate selection practices among college students and in different cultures. It finds that college women feel they have limited options for dating in college - either brief casual hookups or virtually living together. Dating has become less common on campuses as students say they lack time and prioritize group activities over one-on-one dates. This has led some to advocate returning to traditional dating with activities like dinner dates. The document also notes that dating customs vary widely globally and are rare outside Western cultures, with many societies relying on arranged marriages. Changes in sex ratios in countries like China and India have also impacted traditional mate selection systems in those places.
