[W]omen in East Germany essentially stopped having children all together. In a paper from 1994 detailing the immediate evolution of East German fertility in the context of the reunification process, Nicholas Eberstadt shows how births in East Germany indeed did fall dramatically. From 1988 to 1992 the total number of live births fell from 215700 to 88300 which translates into a drop in the crude birth rate from 12.1 to 5.6.

According to Eberstadt and given the information available at the time, the drop was especially severe because fertility dropped sharply among women aged 25-34 and thus among those women in their prime age with respect to childbearing. Furthermore, Eberstadt also shows how marriage rates declined sharply during the transition from communism. Marina A. Adler notes that the highly insecure environment following communism made women reluctant to engage in the kind of long term commitments which marriage and child rearing constitutes. In fact, the almost effective halt in childrearing occuring in East Germany is not so unique in the general sense since the fall of communism also marked a decisive structural break in the context of the fertility behavior of an entire generation of women all across the Eastern European edifice. In this sense, Sobotka offers a comprehensive view of the drivers of the fertility transition in the context Eastern Europe.
The ultimate effect of the shift in an Eastern Germany context was remarkable; Eberstadt estimates that the TFR had fallen to an astonishing 0.98 in East Germany by 1991.
The various waves of residents in the neighbourhood, from a range of diverse cultural and ethnic backgrounds, have also left their traces on the neighbourhood. The presence of two synagogues, the Kiever (1926) and the Anshei Mink (1930), are reminders of the area’s early Jewish population. The bright and colourful building colours, however, have been attributed to the influence of the Portuguese community that arrived later in the early 1960s.

During the first decade of the 20th century, Toronto became home to more than 15,000 displaced Jews from South and Central Europe. Between 1905 and 1910, many Jewish families moved out "the Ward" (an overcrowded immigrant reception area between Yonge and University) and settled in Kensington. Families purchased small row houses from the previous working-class British and Irish immigrant residents. Many opened small businesses in the area and the market was established.
Since Jews were restricted from many services and lacked social benefits, the Jewish community established their own societies, hospitals and other services through the synagogues in the area. The Jewish presence in Kensington Market declined in the 1950s and early 1960s when they moved up and out to other areas of the city.
Following the Second World War, between 1945 and the early 1960s, Canada became home to more than 2.7 million immigrants; of which one quarter settled in Toronto. Poles, Ukrainians, Italians and Hungarians moved into the Kensington Market area. The largest and most important ethnic group to establish itself here were the Portuguese.
Immigrants were attracted to the neighbourhood because of the availability of affordable housing for rent or sale, the proximity of the area to public transportation and work opportunities, and the presence of an ‘old world’ market.
In 1962, Canada amended its Immigration Act to allow a more egalitarian process based on economic and educational factors. As a result, many new groups of immigrants from poorer countries moved into Kensington and opened shops: Afro-Caribbeans (mostly Jamaican), Chinese and East Indian. Kensington Market became a true microcosm of Canada’s ethnic mosaic.

Dry Climate Disconnected the Laurentian Great Lakes
Recent studies have produced a new understanding of the hydrological history of North America’s Great Lakes, showing that water levels fell several meters below lake basin outlets during an early postglacial dry climate in the Holocene (younger than 10,000 radiocarbon years, or about 11,500 calibrated or calendar years before present (B.P.)). Water levels in the Huron basin, for example, fell more than 20 meters below the basin overflow outlet between about 7900 and 7500 radiocarbon (about 8770–8290 calibrated) years B.P. Outlet rivers, including the Niagara River, presently falling 99 meters from Lake Erie to Lake Ontario (and hence Niagara Falls), ran dry This newly recognized phase of low lake levels in a dry climate provides a case study for evaluating the sensitivity of the Great Lakes to current and future climate change.

Lakes without overflow, such as these lowstands in the GLB, can only be explained by a dry climate in which water lost through evaporation exceeded water gained from direct precipitation and catchment runoff. The dry regional climate that forced the lakes into hydrologic closure must have been substantially drier than the present climate. Hydrologic modeling of the present lakes shows that current mean annual precipitation would have to decrease by about 25% in the Superior basin and by about 42% in the Ontario basin, in conjunction with a 5ºC mean temperature increase, to achieve lake closure [Croley and Lewis, 2006]. Paleoclimate simulations and reconstructions using pollen [Bartlein et al., 1998] and stable isotopes [Edwards et al., 1996] indicate that climate in the GLB (Figure 2c) was drier than present at 7900 radiocarbon (8770 calibrated) years B.P. Termination of the lowstand episode about 7500 radiocarbon (8300 calibrated) years B.P. coincides with the onset of a wetter climate as atmospheric circulation adjusted to the rapidly diminishing ice sheet [Dean et al., 2002] and moist air mass incursions from the Gulf of Mexico became more frequent.
The discovery that the Great Lakes entered a low-level phase without having connecting rivers during the early Holocene dry period demonstrates the sensitivity of the lakes to climate change. The closed lakes of this phase occurred when the Great Lakes entered their present nonglacial state. Thus, the closed lakes afford a valuable example of past, high-amplitude, climate-driven hydrologic variation upon which an improved assessment of lake-level sensitivity in response to future climates can be based.
