When people ask what percentage of the population has AIDS, they usually mean HIV, the virus that can lead to AIDS if left untreated. The distinction matters: HIV is a retrovirus that attacks immune cells, while AIDS is the advanced stage of infection when the immune system is severely damaged. Modern antiretroviral therapy can suppress HIV to undetectable levels, meaning the virus cannot be transmitted sexually and the person does not progress to AIDS. So the percentage with HIV is higher than the percentage with AIDS, and both numbers change with testing, treatment access, and prevention efforts.
