Demographics for 1950 Census in 2 communities in Pennsylvania

I would like to obtain demographic data (race and ethnicity) in 1950 for Webster, PA (zip code 15087) and Donora, PA (zip code 15033).There were approximately 14,000 people living in both communities in 1948. I am not sure how to access the 1950 Census data for these 2 zip codes- and whether there is information on race for both communities. Thank you for your advice!
