All Cities 



From the chart portraying the changes in population, number of industrial 

 employees, and establishments in Massachusetts cities, it will be seen that 

 there has been a continuous upward trend in population. The number of in- 

 dustrial employees displays the same upward tendency, closely paralleling the 

 population curve until 1920. Since that date there has been a decisive decline 

 in the number of industrial employees, especially in the period between 1927 

 and 1933, emphasized by the intervening years of business depression. The 

 number of establishments was on the upward trend until 1895. Due to the 

 change in the statistical enumeration there was a sharp decline in the number 

 of establishments between 1895 and 1905. From 1905 there was a slight up- 

 ward trend to 1920, since when a declining movement has been in progress to 

 the end of the period.
