}}The First Amendment (Amendment I) to the United States Constitution establishes a formula for determining the appropriate size of the House of Representatives following each constitutionally mandated decennial census.
The amendment as adopted in 1791 reads as follows:
|“||After the first enumeration required by the first article of the Constitution, there shall be one Representative for every thirty thousand, until the number shall amount to one hundred, after which the proportion shall be so regulated by Congress, that there shall be not less than one hundred Representatives, nor less than one Representative for every forty thousand persons, until the number of Representatives shall amount to two hundred; after which the proportion shall be so regulated by Congress, that there shall not be less than two hundred Representatives, nor more than one Representative for every fifty thousand persons.||”|
