The stellar populations of a field near NGC 6171 are studied. Two-color diagrams are presented, and from these an interstellar reddening is determined with the constant value of 0.30. The stars are classified as main sequence stars and late type giants of population I and as metal-poor main sequence stars. Density functions were determined for the different groups. Negative gradients were found for population I stars, with the gradient for giants steeply declining when approaching the solar neighborhood and flattening with increasing distance. The metal-poor stars up to 3 kpc show an almost constant density. The luminosity functions of the main sequence stars were derived for 0-1 kpc and 1-2 kpc, and the values for population I are found to be lower than in the solar neighborhood.
