What is a primary reason why data on undocumented Latin American workers' sports participation are scarce?

• A. They rarely participate in sports
• B. Reliable data are difficult to obtain
• C. They are all in formal leagues
• D. They are well-studied in other contexts

Answer: (B)

Data on undocumented Latin American workers' sports participation are scarce mainly because obtaining reliable data from this group is difficult. Undocumented workers often avoid government surveys and formal records out of fear of exposure, detention, or deportation, which leads to undercounting in official statistics. Many work informally, move frequently, or lack stable contact information, making them hard to reach with surveys. Language barriers and distrust of researchers can further suppress responses, and ethical concerns about confidentiality limit what can be collected. All of this produces incomplete, biased data, so reliable information is hard to obtain. The scarcity isn’t because participation doesn’t happen or because they’re all in formal leagues, nor because they’re well-studied elsewhere; it stems from the challenges of capturing this population in data.
