Editing Emmaus, Pennsylvania (section)

===20th and 21st centuries===
In 1940, public census statistics showed that 6,731 people lived in Emmaus. The population of the borough has since nearly doubled to 11,467 as of the [[2020 United States census|2020 census]]. Housing construction has reached the borough line in all directions so significant continued population growth in the borough is unlikely. Outside the borough line, however, the local population continues to grow, especially in neighboring [[Lower Macungie Township, Pennsylvania|Lower Macungie Township]]. Consequently, growth in the Emmaus [[ZIP Code]] continues to expand but not within its borough limits.
