As I’ve shown previously, the size of the parcels used makes a big difference in the calculation of population-weighted density, which makes comparing cities difficult internationally. Rather than divide the total population of a city by the entire city area (which usually includes large amounts of sparsely populated land), population weighted density is a weighted average of population density of all the parcels that make up the city. Why Population Weighted Density?Īs discussed in previous posts, population-weighted density attempts to measure the density at which the average city resident lives. It also shows a breakdown of the densities at which these cities’ residents live, and includes a set of density maps with identical scale and density shading. This post calculates the population-weighted density of 53 Australian, European, and Canadian cities with a population over 1 million, plus the three largest New Zealand cities (only Auckland is over 1 million population). in the list of all countries worldwide ranked by population (from the highest population to the lowest population) as of July 1 of the year indicated.Just how much denser are European cities compared to Australian cities? What about Canadian and New Zealand cities? And does Australian style suburbia exist in European cities? World Population: Total World Population as of July 1 of the year indicated. Urban Population: Population living in areas classified as urban according to the criteria used by each country.Ĭountry's Share of World Pop: Total population in the country as a percentage of total World Population as of July 1 of the year indicated. Urban Pop % : Urban population as a percentage of total population. It is calculated as the average number of children an average woman will have during her reproductive period (15 to 49 years old) based on the current fertility rates of every age group in the country, and assuming she is not subject to mortality.ĭensity (P/Km²): (Population Density) Population per square Kilometer (Km²). This parameter provides an indication of age distribution.įertility Rate: (Total Fertility Rate, or TFR), it is expressed as children per woman. Median Age: age that divides the population into two numerically equal groups: half of the people are older than the median age indicated and half are younger. A negative number means that there are more emigrants than immigrants. Migrants (net): The average annual number of immigrants minus the number of emigrants over the preceding five year period (running from July 1 to June 30 of the initial and final years), or subsequent five year period (for 2016 data).
For all other years: average annual numerical change over the preceding five year period. Yearly Change: For 2023: absolute change in total population (increase or decrease in number of people) over the last year (from Jto June 30 2023). For all other years: latest year annual percentage change equivalent assuming homogeneous change in the preceding five year period, calculated through reverse compounding. Yearly % Change: For 2023: percentage change in total population over the last year (from Jto June 30 2023). World Population Prospects: The 2022 Revision. Population: Overall total population (both sexes and all ages) in the country as of July 1 of the year indicated, as estimated by the United Nations, Department of Economic and Social Affairs, Population Division. Year: as of July 1 of the year indicated. This value can differ from the Yearly % Change shown in the historical table, which shows the last year equivalent percentage change assuming homogeneous change in the preceding five year period. The Yearly Population Growth Rate chart plots the annual percentage changes in population registered on July 1 of each year, from 1951 to 2023.
The Population of the United States (1950 - 2023) chart plots the total population count as of July 1 of each year, from 1950 to 2023. The United States Population (Live) counter shows a continuously updated estimate of the current population of the United States of America delivered by Worldometer's RTS algorithm, which processes data collected from the United Nations Population Division.
