##Evidence:
Percentage of male clients = (number of male clients / total number of clients) * 100. Male refers to gender = 'M'. A3 is the region name, A2 is the district name, and A4 contains the number of inhabitants.

Question: What is the district name, number of inhabitants, total number of clients, number of male clients, and percentage of male clients for the most populated district in the south Bohemia region?
Evidence: Percentage of male clients = (number of male clients / total number of clients) * 100. Male refers to gender = 'M'. A3 is the region name, A2 is the district name, and A4 contains the number of inhabitants.
