During this time the number of villagers fluctuated-
By 1900 the numbers had increased, then began period where the numbers constantly decreased until 1931.
The cause was W.W.I (1914-1918) & W.W.II (1941-1945), and emigration, mostly to America.
In 1944 the German population was forced to leave Glogonj.
From December 1945 till 1948 about 400 families were colonized in Glogonj, most are from Macedonia.
Between 1948-1953 some of the new colonists, because they couldn't find permanent housing - returned back in Macedonia.
From the 1950's until 1981 the population continued to increase.
Between 1981 and 1991 numbers start to decrease again. This time the reasons are: the number of births are decreasing, people find work in cities and have to move. And many others move abroad.
