House of People. It shall consist of—

(a) not more than 530 chosen by direct election from territorial constituencies in States, and,

(b) not more than 20 to represent Union territories, chosen in such manner as Parliament may by law provide.

It further provides that:

(a) Each State shall be allotted number of seats in Lok Sabha in such manner that the ratio between number of seats and population of the State is, so far as practicable, the same for all States. This is, however, not applicable for the allotment of seats in the House of the People to any State with a population up to six millions.

(b) Each State shall be divided into territorial constituencies in such manner that the ratio between population of each constituency and number of seats allotted to it is, so far as practicable, the same throughout the State.

For the purposes of allotment of seats, the population of States shall be taken to be the same as ascertained at the last census. The present figure has been arrived at on the basis of 2001 Census. This is meant to secure uniformity in the scale of representation for the States in the Lok Sabha.

Under Article 330 of the Constitution, seats are to be reserved in the House of the people for the Scheduled Castes and the Scheduled Tribes.
