"60% of the Median" can easily be a zero number of elements from the set.
In this case, median means "sorted by income, at which point have we divided the entire dataset in half". For a dataset with more than 2 elements (so 3 elements minimum), you can construct a dataset for which any below-100% of the median of the dataset is not represented in the dataset.
The easiest example would be using "99% of the median" and [9.999, 10, 11]. Median is 10, 99% of the median is 9.9, the smallest sample is 9.999.
60% of the median income basically means "the lowest 50% income bracket should not have more than 40% deviation". Or rather; the lowest possible income is bigger than 60% of the lowest earner of the top 50% of society.
