TREND IN MASSACHUSETTS INDUSTRIES 



11 



Trend in Population, Industrial Establishments, and Wage Earners, 1837 - 1933 



1895 = 100 



Revere. There was a very rapid 

 increase in total population through 

 most of the period, evidently due in 

 large part to residential and recrea- 

 tional developments. The number of 

 industrial employees had an irregular 

 trend, rising until 1895, declining to 

 1910, reaching its peak in 1927, and 

 declining again during the depression 

 period. The number of industrial 

 establishments increased from 1905 

 to 1920 and declined thereafter. 



Salem. The population, after an 

 irregular rise, reached its peak in 1910 

 and remained practically stationary 

 thereafter. The number of industrial 

 employees rose irregularly until 1910, 

 declined thereafter up to 1927 and 

 unlike many other cities, showed an 

 increase in 1933. The number of in- 

 dustrial establishments, with a few 

 minor interruptions, has shown an ir- 

 regular downward movement since 

 1875. 



Somerville. There has been a 

 steady upward movement in popula- 

 tion through the entire period; while 

 the number of industrial employees 

 increased until 1920, declined in 1927, 

 and showed no change in 1933. Be- 

 tween 1905 and 1920 there was an in- 

 crease in number of industrial estab- 

 lishments and a slight decline there- 

 after. 



Springfield. The population 

 maintained a regular upward move- 

 ment during the entire period; while 

 the number of industrial employees, 

 after a long advance, began to decline 

 in 1920. The increase in number of in- 

 dustrial establishments between 1905 

 and 1920 was followed by an almost 

 equal decline.
