Final answer:
The number 435 will never change because it is the fixed number of seats in the US House of Representatives, established by the Apportionment Act of 1911.
Step-by-step explanation:
The number 435 refers to the total number of seats in the House of Representatives, which has been fixed since the Apportionment Act of 1911. Regardless of the growth of the USA's population, this number does not change because there was a concern that Congress would become too large to function effectively if more seats were added.
The apportionment or distribution of these seats among the states can change based on the official census conducted every decade, which reflects shifts in population. However, the total remains at 435 regardless of whether the US population increases or decreases.
