Article One of the United States Constitution
The Fourteenth Amendment removed the three-fifths rule and ordered the census to count everyone regardless of skin color. It stipulated that males over the age of twenty-one could vote. The Sixteenth Amendment removed the connection between apportionment and direct taxes. The 19th Amendment removed the restriction by sex allowing women to vote. The 26th Amendment reduced the voting age requirement to those 18 years of age and older. But none of these amendments changed congressional apportionment.
