Amsterdam IX (electoral district)

Amsterdam IX was an electoral district of the House of Representatives in the Netherlands from 1897 to 1918.

The electoral district of Amsterdam IX was created in 1897, when the district of Amsterdam, like all other remaining multi-seats districts, was split into single-member districts. The territory of Amsterdam IX roughly corresponded with the neighbourhoods of Oud-West, Frederik Hendrikbuurt and Staatsliedenbuurt, all located in the current borough of Amsterdam-West.^[1]^[2]

Due to Amsterdam's rapid urban expansion into the district's boundaries, its electorate grew rapidly, from just 5,215 in 1897 to 27,317 in 1917, making it the largest electorate of any district at that time.^[3]^[4]

The district of Amsterdam IX was abolished upon the introduction of party-list proportional representation in 1918.
