You wouldn’t have to know people, but yes there’s a good chance of it. For example, consider if the unemployment rate is 1/300,000,000 (ie. One person in the US is unemployed). Then only the people that know that one person would know an unemployed person. However, the percentage is high enough that everyone should expect to know a couple unemployed people. If the rate is 3% and everyone knows 200 people well enough to know their employment status, then you should expect to know 6 unemployed people.
