Low-mass galaxies are under-represented in galaxy redshift surveys because of their lower contribution to the cosmic luminosity density; considering low mass to be less than the stellar mass of the Large Magellanic Cloud. However, they clearly dominate by number density and are significant for testing models of galaxy evolution. Key measurements are the galaxy stellar mass function and clustering properties, which are difficult to determine accurately to the lowest masses. The Sloan Digital Sky Survey and Galaxy And Mass Assembly survey have made progress on these measurements. The next decade will see a dramatic improvement in cosmological measurements possible with low-mass galaxies through Euclid and the Square Kilometre Array.
