Beginning with the early postwar years, Polish has been the language of all but a very few citizens. Grouped with Czech and Slovak in the West Slavic subgroup of the Slavonic linguistic family, Polish uses a Latin alphabet because the Roman Catholic Church has been dominant in Poland since the tenth century. Documents written in Polish survive from the fourteenth century; however, the literary language largely developed during the sixteenth century in response to Western religious and humanistic ideas and the availability of printed materials. In the eighteenth century, the Enlightenment stimulated a second period of advances in the literary language. When the Polish state fell at the end of the eighteenth century, the language played an important role in maintaining the Polish national identity.
In 1988 about 51 percent of Poland's population was female, a statistic reflecting the fact that average life expectancy was about nine years greater for women (66.5 years for men, 75.5 for women). The ratio of men to women was significantly higher (as much as five to two) in rural areas, from which many women migrated to escape poor conditions on private farms. Over a period of years, a lower rural birth rate led to a smaller agricultural work force. Already in 1981, only 55 percent of the rural population was of working age, compared with 63 percent of the urban population. (Working age was defined as eighteen to fiftynine for women, eighteen to sixty-four for men.) In 1991 some 29.4 percent of the overall population was below working age, and 13 percent was past working age. The former figure had fallen since the mid-1980s, while the latter rose in the same period. The 547,000 live births in Poland in 1991 equaled 14.3 births per 1,000 people. However, the 74 deaths versus 100 births recorded that year was a higher ratio than in any recent year. (In the early 1980s, the ratio was less than 50 to 100.)
In the immediate postwar period, Poland's birth rate surged upward and many Poles were repatriated from military duty or imprisonment abroad. This population increase was tempered, however, by continued emigration of ethnic groups such as the Jews and non-Polish Slavs after the war ended. The annual growth rate peaked in 1953 at more than 1.9 percent; between 1955 and 1960, it averaged 1.7 percent before dropping to 0.9 percent in 1965. The growth rate then remained fairly steady through 1980. In the early 1980s, however, Poland's growth rate of 1.0 percent placed it behind only Albania, Ireland, and Iceland among European countries. The population increase in the early 1980s was attributed to childbearing by women born in the postwar upswing as well as to lower death rates.
Although modern Polish was homogenized by widespread education, distribution of literature, and the flourishing of the mass media, several dialects originating in tribal settlement patterns survived this process in the late twentieth century. Among the most significant are Greater Polish and Lesser Polish (upon a combination of which the literary language was formed), Silesian, Mazovian, and Kashubian, which is sometimes classified as a separate language.
Population Growth and Structure
In 1989 Poland had twenty-four cities with populations of at least 150,000 people. Major urban centers are distributed rather evenly through the country; the most concentrated urban region is the cluster of industrial settlements in Katowice District. In 1990 overall population density was 121 people per square kilometer, up from 115 per square kilometer in 1981. The most densely populated places are the cities of ód (over 3,000 people per square kilometer) and Warsaw (about 2,000 people per square kilometer). Urban areas, which contain over 60 percent of Poland's population, occupy about 6 percent of the country's total area. In 1990 average population density in rural areas was fifty-one people per square kilometer, a small increase over the 1950 figure of forty-seven people per square kilometer.
Between 1939 and 1949, the population of Poland underwent two major changes. The deaths, emigration, and geopolitical adjustments resulting from World War II reduced the 1939 population of about 35 million to about 24 million by 1946. Only in the 1970s did Poland again approach its prewar population level. In addition, the ethnic composition of the country was drastically homogenized by the mass annihilation of Polish Jews and the loss of much of the non-Polish Slavic population through the westward shift of the borders of the Ukrainian and Belorussian republics of the Soviet Union.

Later in the 1980s, as many women passed their peak childbearing years, projected growth rates again dropped. From 1985 through 1991, the actual population increase was smaller every year. The actual increase in 1991 was 122,000. Nevertheless, in 1988 one in five persons added to the population of Europe outside the Soviet Union was a Pole. Experts forecast that in the year 2000 Poland would be contributing virtually all the natural growth in Europe's employed population. In 1990 the shape of Poland's population pyramid was expected to remain relatively constant; it was composed of a relatively small base of young people, with a wider component of citizens over age sixty and a bulge in the cohort born during the postwar upswing. In 1990 this group ranged in age from thirty-five to forty-four. At the end of 1991, the total population was estimated at 38.3 million; projected population in the year 2000 was 39.5 million.
The most important change in postwar Poland's population distribution was the intense urbanization that took place during the first two decades of communist rule. The priorities of central economic planning undoubtedly hastened this movement, but experts hypothesize that it would have occurred after World War II in any case. In 1931 some 72.6 percent of the population was classified as rural, with nearly 60 percent relying directly on agriculture for their livelihood. By 1978 those figures had diminished to 42.5 and 22.5 percent, respectively. In the next ten years, the share of rural population dropped by only 3.7 percent, however, indicating that the proportions had stabilized.
In the late 1980s, emigration from Poland was stimulated mainly by poor economic conditions. The 1989 total of 26,000 émigrés dropped to 18,500 in 1990, but the slow progress of economic reform caused the rate to increase again in 1991. In this period, the group most likely to emigrate was healthy men between the ages of twenty-six and thirty who had completed high school or trade school. The majority in this group came from regions of high unemployment and had experience working abroad. In 1991 polls showed that as much as one-third of the Polish population viewed emigration as at least a theoretical option to improve their standard of living.
