From 1792 to 1945, it was mostly populated by Germans, and some Hungarians and Romanians lived there as well. In 1921, the population numbered 4,450 inhabitants, including 4,333 Germans, 63 Hungarians, 39 Romanians, 3 Czechs or Slovaks and 2 Slovenes. In 1944, after the defeat of Axis Powers (World War II in Yugoslavia), one part of German population left from the region, together with defeated German army. The remaining Germans were sent after local imprisonment to internment camp in Knićanin that existed until 1948. After prison camps were dissolved (in 1948), the remaining German population left Yugoslavia because of economic reasons. In the first time period after World War II the village was settled with families that originated from all parts of Yugoslavia. The number of reported inhabitants of the town in 2002 was 7,624. The majority of inhabitants were ethnic Serbs (5,042 or 66.13%), while Macedonians form 19.24% of the population or 1,467 people. The main occupation of the towns' people is in agriculture, as with many other local settlements. However, many of the towns’ inhabitants also work in the factories of the neighbouring city of Pančevo. Since 1960, there is a cultural center (Dom kulture) in Kačarevo. The town is famous for its bacon festival known as "Slaninijada" (slanina means bacon), which is organised by the Tourist Association. The festival was organised for the first time in 1988 and runs on an annual basis during February. For several years, there is the vocal group "Toše Proeski" which is very well known in the Vojvodina. One of the main attractions in the settlement is the artificial Kačarevo Lake (). It is stuated southeast of the center of Kačarevo on the location of the former cattle cemetery, colloquially called the "horse graveyard". The denizens organized themselves and from 2007 began cleaning the area from the underbrush and eventually dug a lakebed. The surrounding area was adapted into the square green oasis with the forested alleys of pines, firs and deciduous trees. The benches and tables are placed between the trees. There are lawns with the rose seedlings, gazebos and a pheasant farm within the complex. The lake itself has a fountain which constantly pours the fresh water into the lake, a springboard, the showers, sunbeds, parasols and a lifeguard service.
