Ben burada bu şekilde kullanırdım sanırım.

Görünüşe göre yoksulluk ölçümü yapılırken "median income"un %50'si veya %60'ı kıstas alınarak ölçüm yapılıyor. Referanstan örnek:

In a 2014 study conducted by the University of NSW’s Social Policy Research Centre (SPRC) on behalf
of the Australian Council of Social Service (ACOSS), using the 50% of median income benchmark, it
was estimated that 2.5 million people including 603,000 children were living below the poverty line
in 2012, after taking housing costs into account (ACOSS, 2014:9). If the benchmark was widened
from 50% to 60% of median income, then 4 million people were considered to be living in poverty.
