An allotment garden (British English), often called simply an allotment, or a community garden (North America) is a plot of land made available for individual, non-commercial gardening or growing food plants. Such plots are formed by subdividing a piece of land into a few or up to several hundreds of land parcels that are assigned to individuals or families. Such parcels are cultivated individually, contrary to other community garden types where the entire area is tended collectively by a group of people.[2] In countries that do not use the term allotment (garden), a community garden can refer to individual small garden plots as well as to a single, large piece of land gardened collectively by a group of people. The term victory garden is also still sometimes used, especially when a community garden dates back to World War II or I.

For various reasons quite a few of the community gardeners do not join an association. Around 1960 their number was believed to be as high as the one of those who were organized. {cf. HESSING 1958} Although there are no statistics available for those gardens I assume that their number has decreased considerably over the past decades and may now be near 100 000 in Germany. Many of these gardens belonged to what was called railroad-agriculture, "Bundesbahnlandwirtschaft" because they were established on lands which the state-owned railroad company holds as reserves for future railroad purposes. {In the 1990s the railroad company felt it would no longer need this land and offered many of these community gardeners, who often were employees of the railroad company, to buy the land for their garden, and many did.} In 1990 such community gardens counted for about seven percent of the total area in Berlin (West). {about 3 500 allotment gardens on about 150 hectares} Other non-organized community gardens are located on areas which belong to private land owners, public institutions, churches, and large companies.

In 1996 about 78 000 allotment gardens belonged to the state-wide allotmentholders union. {cf. the table 'Kleingaerten im Bezirk' , Berliner Gartenfreund, 5/5, May 1996, which counts 78 043 allotment gardens for Berlin. The number of inhabitants was 3 475 392, this is one allotment garden for 44 to 45 inhabitants} This is about 10 000 more than in 1931 for the 'Provinzialverband Groß-Berlin', the provincial union of Greater Berlin. In the same year the union merged with the allotmentholders union in the state of Brandenburg, and now represents the people who operate some 160 000 small gardens.{this number was given by FRIEDRICH, the head of the Brandenburg union of allotment holders, at a meeting by the Naulin-Stiftung, Naulin-Foundation, in October 1995; in 1931 about 10 000 allotment holders (cf. GUTMANN 1931:89), in 1995 about 75 000 (cf. GARTZ 1995 and membership table in Der Fachberater, 43, August 1994, 145), were organized in the provincial union of Brandenburg}

As part of the urban culture allotment gardens mirror the dynamics of urban development. So their number decreased between 1950 and 1960 since the need to produce fruit and vegetable for economic reasons on one's plot gradually ceased. If community gardens vanished after 1960 because the land was needed for new schools, for new residential developments, for new roads, new commercial and industrial districts, for new track and field facilities, and even for new urban parks,{cf. GR ÖNING, Gert: Tendenzen im Kleingartenwesen, dargestellt am Beispiel einer Großstadt, Beiheft zu Landschaft + Stadt, 10, Stuttgart 1974} then they re-emerged somewhere else in town with the help of the municipal authorities.
