And don't forget "jobless" people are only that fraction of people that are still actively seeking employment or are qualified to seek unemployement benefits. Once you are no longer eleigible for benefits, you drop off the radar.
This is not exactly correct, at least not for US. In US calculation of unemployment also uses household surveys and surveys of employers. So one does not have to be eligible for benefits in order to be count in unemployment statistics.
The Bureau of Labor Statistics measures employment and unemployment (of those over 15 years of age) using two different labour force surveys[75] conducted by the United States Census Bureau (within the United States Department of Commerce) and/or the Bureau of Labor Statistics (within the United States Department of Labor) that gather employment statistics monthly. The Current Population Survey (CPS), or "Household Survey", conducts a survey based on a sample of 60,000 households. This Survey measures the unemployment rate based on the ILO definition.[76] The Current Employment Statistics survey (CES), or "Payroll Survey", conducts a survey based on a sample of 160,000 businesses and government agencies that represent 400,000 individual employers.

But I do agree with you that real unemployment (or underemployment) is probably higher than the official statistics.

We can't provide jobs, we can't provide drinking water or food, housing, health services, etc... to hundreds of millions of people. How can anyone say that almost doubling the world population in the next 40 years is *sustainable"?
I do not think this is a right question to ask, I mean the question about jobs. First, there is a theoretical question, can be people provided with adequate shelter, food, water etc using existing resources and modern technologies, is it theoretically possible? I do not know answer to this question. From what you have written, I guess you say it is impossible. I really would like to see some studies on this, if they exist.
If the answer is no, than the problem of overpopulation should be approached by reducing population. High birth rate is usually a sign of agricultural societies. In such societies people need more children as free labor force in subsistence farming. In industrial societies birth rates are usually low. And there is a correlation between level of education and birth rates. So the approach could be mechanization and increasing education.
If answer is yes, then this means that the problem is not overpopulation but distribution and organization of the process of production. Maybe productive forces of society are so developed that few can provide for many. In this case, the whole notion of distribution according to labor contribution maybe outdated. There is another problem, the problem of “overproduction crisis”, the business cycles, the paradox of misery in the land of plenty, the things that happened during great depression. And this is not a problem of overpopulation, but of social organization.
