How many people have the Bombay blood type?

The Bombay Blood Type (BBT): This serotype occurs in one in 10,000 Indians, or in one hundredth of a percent of people (0.01%). In Europeans, the occurrence is even rarer, at one in 1,000,000, or one ten thousandth of a percent (0.001%). Individuals with BBT do not have a ‘H’ antigen, and cannot make the ‘A’ and ‘B’ antigen. They can only accept similar blood, meaning those of the ABO serotype cannot donate their blood to them.

World population: 7.8 Billion

Population of India: 1.352 Billion; Bombay blood: 135,200

World population without India: 6.448 Billion; WPWI Bombay Blood: 6,448

This is only an estimate as African and Asian averages are not available.

How many of these Bombay blood group O(h) people are also rh negative, O(h)-?

Much material is flawed:

The probability of finding a person with Bombay phenotype is one for every 250,000 people worldwide. India has the highest number with one Bombay blood type per 7600 people.[9] After its discovery in1952,[5] Bombay blood group has been reported by various other workers in different parts of India and even in other Asian and European countries.[10] According to Sathe et al., 179 cases of Bombay phenotype were detected of which 112 was found in Maharashtra, followed by 14 cases in Karnataka, 8 cases in Andhra Pradesh, 6 cases in Goa, 5 cases in Gujarat and so on in decreasing order. All the cases were hospital cases and random population screening was not done.[11]

This would mean 31,200 people worldwide and “out of those”, 177,895 in Inda?
