Geo Notes – Oct/12 Canada’s Human Face - Canada’s population: Canada’s population continues to grow and age, and it is also moving in new geographic, social, and religious directions. There is also a high aboriginal birth rate. The population exceeded 33 million in 2009. The most growth has taken place in BC, western Canada, and Ontario. Canada’s demography has changed. Demography is the study of human populations, including their size, composition, distribution, density, growth, and related socio-economic characteristics. Immigration plays a major role in these demographic and social changes. A census occurs every 5 years to estimate the population size. Undercounting can occur, which is when some households are missed and the estimated population is low. There are three factors that account for Canada’s population growth – natural increase, territorial expansion, and immigration. Natural increase used to be the primary factor, but birth rates have decreased, and now immigration is the primary factor in population growth. The last territorial expansion took place in 1949 when Newfoundland joined confederation. Canada’s population density, which is the total number of people in a geographic area divided by the land area, is very low (3.5 people/km2). The reason for this is that most of the land in Canada is not capable of supporting human settlement. - Population distribution is the dispersal of people within a geographic area. Canada’s population is unevenly distributed. The area around the border is Canada’s ecumene (the portion of the land that is settled). There is a highly concentrated population core surrounded by more thinly populated zones. ON and QC contain the majority of the population. These regions have a lot of political force and this is a source of regional alienation. Canada’s core population zone lies in the great lakes-st. Lawrence lowlands. This is Canada’s most densely populated area. Its economy is based on manufacturing and its agriculture lands contain the most fertile farmlands. The secondary core zone occupies the southern portions of the Appalachian uplands, the Canadian shield, the interior plains, and the cordillera. This is a band 300km north of the US border. This is a moderately populated zone and the population is increasing slowly and unevenly. A major city here is Vancouver. The third zone is sparsely populated and is located in the boreal forest (Canadian shield, interior plains, cordillera). Fort McMurray, AB is the only major city here. It is a resource town, which is an urban place where a single economic activity focused on resource extraction (ex. mining, logging) dominates the local economy. A resource town can also be a town built near a mine to house the workers and their families. Whitehorse and Yellowknife are also in this zone and they are regional service centres, which are urban places where economic functions are provided to residents living within the surrounding area. The fourth zone is an almost uninhabited zone with isolated centres. Most people here reside in native settlements, which are small aboriginal centres often found on reserves. This zone has the lowest population density. It is the least productive area in the country. A major city here is Labrador City. There is a high rate of natural increase in the aboriginal population, but there is also a lot of emigration. - Urban population: Canada is an urban country – 80% of the population lives in cities and towns. There has been a shift from rural to urban, and this began in the 1920s. A census metropolitan area is an urban area with a population of at least 100,000, together with adjacent smaller urban centres and rural areas that have a high degree of economic and social integration with the larger urban area. The majority of Canada’s population resides in CMAs and there are 33 CMAs. Atlantic Canada is the least urbanized part of Canada. Cities are attractive because they are where most business and employment opportunities are found, and amenities are readily available. A city’s prosperity is determined by the creativity of its business and university communities. Urbanization is associated with economic development, so the rate of urbanization has varied across Canada. The shift from rural to urban communities is associated with two factors – the declining numbers involved in agriculture due to mechanization, and the increase in job opportunities in urban places. This has created the problem of urban sprawl and has resulted in conflict between farmers and urban people. - Population change: Population change has three components – births, deaths, and migration. Population increase is the sum of natural increase and net migration over a given period. Population growth is the rate at which a population is increasing or decreasing in a given period due to natural increase and net migration and it is expressed as a percentage change over time. The rate of natural increase is the difference between the crude birth rate (CBR) and the crude death rate (CDR). CBR (fertility rate) is the number of live births per 1000 people in a given year. CDR (mortality rate) is the number of deaths per 1000 people in a given year. Net migration is the difference between in- and out-migration. The push-pull model says that negative factors in the migrant’s current location push them to migrate and positive factors in the location of destination pull the migrant to relocate. - The baby boom began after WWII and lasted 20 years before the baby bust (1945-1965). It is a large cohort and has driven a lot about Canadian society in recent decades (school expansion and contraction, housing market). David Foot came up with the boom, bust, and echo idea. There was a large boom in population, then there was a bust, and the echo is boomers’ babies. - Natural increase is determined by the number of births minus the number of deaths. As Canada became an industrial country, birth rates decreased. The death has also increased due to better health care, but is slowly increasing again because of an aging population. The birth rate has decreased due to three reasons – the shift of people from rural areas to cities, the increase in the number of women in the labour force, and family planning (birth control). Canada has a low rate of natural increase. - The demographic transition theory describes population change in industrial societies. This theory is based on the assumption that changes in birth and death rates occur as a society moves from a pre-industrial to an industrial economy. These demographic changes occur in five phases: 1) Late pre-industrial – H
