Pakistan has just more than half as many people as the United States but if the U.S. stopped accepting new international immigrants, at Pakistan's current rate, it will surpass the United States in population within 20 years. Pakistan is one of the world's most rapidly growing countries with an annual population growth rate of 2.4 percent. This rate of growth results in a doubling of a population every 30 years. Pakistan's population was a mere 32.5 million people when it won independence in 1947. In the sixty years since independence its population increased by more than 120 million to reach 166 million people. The current rate of growth for the United States, which is influenced by movement of a large number of people into the country, yields a doubling time of 120 years. For the U.S. and Pakistan, persistence of these same rates of population growth for 115 years would result in a staggering population of more than 2 billion for Pakistan At that time Pakistan would have a population that is 3.3 times that of the United States.

"Drawing on the latest research and statistics, the third edition of Population Change in Canada offers a comprehensive, up-to-date survey of Canadian demography from the sixteenth century to the present day. Beaujot and Kerr's insightful narrative lays the groundwork by outlining key demographic concepts as well as the fundamental population processes--mortality, fertility, and immigration--before moving on to explore in greater depth issues of population growth, distribution, and aging and finally the social, cultural, economic, and political consequences of population change. Accessible and enlightening, Population Change in Canada offers students the foundation they need to fully understand population change and to prepare to meet its challenges both now and in the future."--

Within the next 2 decades US pop will undergo substantial changes both in size & age structure. Persons in their 20's will increase; those between 35-44 will decrease; & those between 45-64 will increase. Large increases will occur in the senior citizens age group, & a sharp increase in the number of teenagers & children under 10 yrs of age may be expected. AAAPSS.

Within the next two decades American population will undergo sub stantial changes both in size and age structure. Persons in their twenties will increase; those between 35 and 44 will decrease; and those between 45 and 64 will increase. Large increases will occur in the senior citizens age group, and a sharp increase in the number of teenagers and children under 10 may be expected.

Abstract  In this paper we return to an issue often discussed in the literature regarding the relationship between highway expansion and population change. Typically it simply is assumed that this relationship is well established and understood. We argue, following a thorough review of the relevant literature, that the notion that highway expansion leads to increased population growth in the vicinity of the improved infrastructure finds only weak and often conflicting support. Using data on all major highway expansions in Wisconsin covering the period from the late‐1960s through the 1990s from the Wisconsin Department of Transportation (WisDOT), and census data at the minor civil division (MCD) level covering the period 1970 to 2000, we deploy the analytical tools of geographic information system (GIS) software, and theory from the expanding literature in spatial analysis and modeling, to take a fresh look at this relationship. Our analysis reveals that there is a modest relationship between highway expansion and population growth among MCDs within 10–20 miles of the expanded major highway. The causal structure, however, is complex. Our starting hypothesis argues that population growth precedes highway expansion as frequently as population growth results from highway expansion, but the data show otherwise. The dominant causal influence appears to flow from highway expansion to population growth.
