cities pasteurizing from 50 to 100 per cent of their milk, and a gain 
in the average percentage pasteurized over the 1924 figures. Every 
city but one reports pasteurized milk in 1930. Of these 125 cities, 
32.8 per cent reported from 90 to 100 per cent pasteurized milk in 
1924 and 46.4 per cent were in the same group in 1930.

Table 4 gives the percentage of milk reported pasteurized in 302 
cities for the years 1924 and 1930. The cities are listed in order of 
their population according to the 1930 census. It is interesting to 
compare the 1924 figures with the 1930 figures and to note the in- 
crease in the percentage of milk pasteurized in cities of less than 50,000 
population.
