Question

why most of the democracies take form of representatives democracy?

Answer 1

Representative democracy (also indirect democracy, representative republic, or psephocracy) is a type of democracy founded on the principle of elected officials representing a group of people, as opposed to direct democracy. Nearly all modern Western-style democracies are types of representative democracies.
Representative democracy is often presented as the most efficient form of democracy possible in mass societies. It arguably allows for efficient ruling by a sufficiently small number of people on behalf of the larger number. Representatives voting on behalf of the people allows for a monetary benefit as there is lessened use of polling stations, vote counters, etc. The government is generally responsible for paying for the wages of the representatives and would have to cover the substantial cost of a direct democracy. This system of governance is also time efficient as decisions can be made by a select few, knowledgeable group of legislators rather than the entire country's population.
So this are some reasons why most of the democracies take representatives form of democracy.
