What's the population of Chinese and Portuguese that have original roots in Guyana thorough indentureship?
In what way the "The 2001 census suggests that they [Indians] also remain less educated." I know you do not understand to interpret statistics but I am willing to help you out for free...just today though.
You can look at various regions. Compare region 6 with 10 as an example.
You have a complete inability to interpret data concerning socio economic or political factors, so I don't need or want your help.
100% of the Portuguese Guyanese are the descendants of indentures, as are the vast majority of Chinese Guyanese. But you have difficulty understanding this, as their circumstances have moved so vastly beyond that of Indians.
So rather than worrying about Africans, focus on Indians, who have serious problems rooted in the same colonial history. Indo Guyanese have the HIGHEST suicide rates in the world, higher than their counterparts in Suriname and Trinidad, so you cannot ascribe this phenomenon to culture. Its is the specific circumstances of rural Indo Guyanese. Happy people do NOT kill themselves.
