Quite a telling assumption there.
One might say the same to you, though.
The school in question, the Mahalia Jackson School, has an Economic Need Index of 95, as shown on the linked dashboard. So 95% of the families in this school’s census tract have income below the poverty line.
The Office of the New York State Comptroller’s public data also shows that families with female heads of household (and no spouse) experience poverty at more than two times the rate for all families and four times the rate of married couples.
So, social trends may not show the whole picture in a specific location.

(A school’s Economic Need Index (ENI) determines the likelihood that students at the school are in poverty. The ENI is calculated as follows: If the student is HRA-eligible or living in temporary housing, the student’s Economic Need Value is 1.0. For high school students, if the student has a home language other than English and entered the NYC DOE for the first time within the last four years, the student’s ENI value is 1.0. Otherwise, the student’s Economic Need Value Is based on the percentage of families (with school-age children) in the student’s census tract whose income is below the poverty level, as estimated by the American Community Survey 5-Year Estimate. The student’s Economic Need Value equals the decimal value of this percentage (e.g., if 62% of families in the census tract have income below the poverty line,the student’s Economic Need Value is 0.62). The school’s Economic Need Index is the average of its students’ Economic Need Value).
