Which of these factors is closely linked to sports participation among certain ethnic groups?

The factor closely linked to sports participation among certain ethnic groups is the popularity of certain sports in cultural backgrounds. Cultural influences play a significant role in which sports are favored and practiced within various ethnic communities. For example, individuals from countries where cricket is a dominant sport may be more inclined to participate in cricket when they settle in different regions, fostering a continuity of cultural traditions through sport.

This connection highlights how cultural heritage shapes preferences and participation levels. Certain sports may resonate more with individuals due to shared history, community events, and cultural celebrations. As a result, this can lead to higher engagement in those specific sports within particular ethnic groups, reinforcing the link between cultural background and sports participation.

The other options, while relevant in different contexts, do not capture the same level of direct influence stemming from cultural identity and community practices as this factor does.
