1. Consider the data presented below, which represent the average householdincomes earned by immigrants from various Asian countries in 2019 (Source: U.S. Census).

Evaluate critically the following statements:

1. "The major reason we see such wide differentials in these incomes is discrimination. E.g., there is less discrimination against Indians than against Burmese."
2. "Indians are on the top of this list because they work harder than Pakistanis and Koreans."
3. "The average ability of immigrants from a specific country to use the English language and their level of education likely explains a considerable proportion of these differences in income."
4. "Immigrants are self-selected and constitute a non-random sample of the populations of the countries from which they come. Thus, intelligent comparisons between immigrants from various countries, or comparisons between immigrants and native residents of the U.S., are difficult to make."
5. "These are household incomes; some of these differences might disappear if we corrected for the number of earners in each household."
