With a dot density map, the individual points mapped will quickly reveal how many competitors are present and areas that might be underserved. Say that, for example, you plan on opening a new location for your bookstore franchise one of the factors you’ll be considering is the proximity to similar businesses and how many libraries are present in a given neighborhood. #2 – Dot Density Maps for New Business Planningĭot density maps can also be crucial in business planning. Urban planners can rely on dot density maps to monitor shifts in densest areas across states and counties, and determine the need for new infrastructure, parks, schools, and more public services. When looking at the dot density map of a city’s population we can easily tell that the vast majority of people are concentrated within the city borders and as we pan out into the suburbs the dots appear further apart, indicating that those areas are less densely populated. #1 – Dot Density Map for Urban Planningĭot density maps come in very handy when, for example, we are trying to quickly grasp where the majority of a certain population lives. If you are looking for the best tool to create a dot density map, Maptive is world-class mapping software that offers a variety of features that make the process easy and efficient. They are ideal for seeing how things are distributed over a geographical region and the relative density of data sets. It might be helpful to know that dot density maps are sometimes also referred to as dot distribution maps. This becomes very helpful when the amount of individual data points becomes too great to be displayed individually. In a one-to-many dot map, each dot represents aggregate data values.In a one-to-one dot map, each dot represents the actual locations of an individual business, building, data point, or occurrence of a phenomenon.That might sound confusing, but it’s really very simple: The dot placement on the map can communicate a lot of information about the data, such as its density or distribution.Įvery dot on a dot density map can represent either a one-to-one or one-to-many value. What is a Dot Density Map?ĭot density maps are a type of data visualization that uses dots as a symbol to represent individual data points. The various datasets disaggregated by age are available in two forms: by standard 5-year age groups and single ages.Īdditional outputs, including results from the probabilistic projections, and more detailed metadata will be posted soon after the initial public release.Dot density maps are one of the most common maps we use to visualize the concentration of a specific demographic or type of business or building in a given area. For the first time, the estimates and projections are presented in one-year intervals of age and time instead of the five-year intervals used previously. Special Aggregates also provide additional groupings of countries. For advanced users who need to use these data in a database form or statistical software, we recommend to use the CSV format for bulk download. An online database (Data Portal) provides access to a subset of key indicators and interactive data visualization, including an open API for programmatic access. The main results are presented in a series of Excel files displaying key demographic indicators for each UN development group, World Bank income group, geographic region, Sustainable Development Goals (SDGs) region, subregion and country or area for selected periods or dates within 1950-2100. This latest assessment considers the results of 1,758 national population censuses conducted between 19, as well as information from vital registration systems and from 2,890 nationally representative sample surveys The 2022 revision also presents population projections to the year 2100 that reflect a range of plausible outcomes at the global, regional and national levels. It presents population estimates from 1950 to the present for 237 countries or areas, underpinned by analyses of historical demographic trends. The 2022 Revision of World Population Prospects is the twenty-seventh edition of official United Nations population estimates and projections that have been prepared by the Population Division of the Department of Economic and Social Affairs of the United Nations Secretariat.
