The Global Social Mobility Report 2020 ranked Singapore 20th out of 82 countries studied.
After reading the report, Mr. Tan, a student at the Singapore University of Social Sciences, was
interested to estimate income mobility across generations in Singapore. He surveyed a random
sample of 120 students from the Singapore University of Social Sciences, and collected data
on monthly income of their father and their oldest sibling who is currently working in 2021.
He managed to get 72 pairs of income data, which are given in the Excel data file
“BUS105_mobility”. Based on his observation, he hypothesized that rich children have rich
fathers.
