This study presents a mathematical model to forecast the dynamics of population density uuu and water resources vvv in Uzbekistan from 2025 to 2030, based on historical data from 2010 to 2024. A system of nonlinear partial differential equations (PDEs) is employed to describe the interaction between population growth and water consumption. The model is solved numerically using an implicit finite difference scheme and the tridiagonal matrix algorithm (TMA) with an iterative approach, using real data-derived initial conditions and a Gaussian distribution for the spatial representation of population and water resources. By 2030, Uzbekistan’s average population density may reach , while water resources decline to under a baseline scenario, or with a 0.5% reduction in depletion. The study recommends implementing water-saving technologies, such as drip irrigation, to ensure sustainable resource management in Uzbekistan.

The United States MSA Boundaries data set contains the boundaries for metropolitan statistical areas in the United States. The data set contains information on location, identification, and size. The database includes metropolitan boundaries within all 50 states, the District of Columbia, and Puerto Rico. The general concept of a metropolitan area (MA) is one of a large population nucleus, together with adjacent communities that have a high degree of economic and social integration with that nucleus. Some MAs are defined around two or more nuclei. Each MA must contain either a place with a minimum population of 50,000 or a U.S. Census Bureau-defined urbanized area and a total MA population of at least 100,000 (75,000 in New England). An MA contains one or more central counties. An MA also may include one or more outlying counties that have close economic and social relationships with the central county. An outlying county must have a specified level of commuting to the central counties and also must meet certain standards regarding metropolitan character, such as population density, urban population, and population growth. In New England, MAs consist of groupings of cities and towns rather than whole counties. The territory, population, and housing units in MAs are referred to as "metropolitan." The metropolitan category is subdivided into "inside central city" and "outside central city." The territory, population, and housing units located outside territory designated "metropolitan" are referred to as "non-metropolitan." The metropolitan and non-metropolitan classification cuts across the other hierarchies; for example, generally there are both urban and rural territory within both metropolitan and non-metropolitan areas.

Abstract

The Gallup Poll Social Series (GPSS) is a set of public opinion surveys designed to monitor U.S. adults' views on numerous social, economic, and political topics. The topics are arranged thematically across 12 surveys. Gallup administers these surveys during the same month every year and includes the survey's core trend questions in the same order each administration. Using this consistent standard allows for unprecedented analysis of changes in trend data that are not susceptible to question order bias and seasonal effects.

Introduced in 2001, the GPSS is the primary method Gallup uses to update several hundred long-term Gallup trend questions, some dating back to the 1930s. The series also includes many newer questions added to address contemporary issues as they emerge.

The dataset currently includes responses from up to and including 2025.

Methodology

Gallup conducts one GPSS survey per month, with each devoted to a different topic, as follows:

January: Mood of the Nation

February: World Affairs

March: Environment

April: Economy and Finance

May: Values and Beliefs

June: Minority Rights and Relations (discontinued after 2016)

July: Consumption Habits

August: Work and Education

September: Governance

October: Crime

November: Health

December: Lifestyle (conducted 2001-2008)

The core questions of the surveys differ each month, but several questions assessing the state of the nation are standard on all 12: presidential job approval, congressional job approval, satisfaction with the direction of the U.S., assessment of the U.S. job market, and an open-ended measurement of the nation's "most important problem." Additionally, Gallup includes extensive demographic questions on each survey, allowing for in-depth analysis of trends.

Interviews are conducted with U.S. adults aged 18 and older living in all 50 states and the District of Columbia using a dual-frame design, which includes both landline and cellphone numbers. Gallup samples landline and cellphone numbers using random-digit-dial methods. Gallup purchases samples for this study from Survey Sampling International (SSI). Gallup chooses landline respondents at random within each household based on which member had the next birthday. Each sample of national adults includes a minimum quota of 70% cellphone respondents and 30% landline respondents, with additional minimum quotas by time zone within region. Gallup conducts interviews in Spanish for respondents who are primarily Spanish-speaking.

Gallup interviews a minimum of 1,000 U.S. adults aged 18 and older for each GPSS survey. Samples for the June Minority Rights and Relations survey are significantly larger because Gallup includes oversamples of Blacks and Hispanics to allow for reliable estimates among these key subgroups.

Gallup weights samples to correct for unequal selection probability, nonresponse, and double coverage of landline and cellphone users in the two sampling frames. Gallup also weights its final samples to match the U.S. population according to gender, age, race, Hispanic ethnicity, education, region, population density, and phone status (cellphone only, landline only, both, and cellphone mostly).

Demographic weighting targets are based on the most recent Current Population Survey figures for the aged 18 and older U.S. population. Phone status targets are based on the most recent National Health Interview Survey. Population density targets are based on the most recent U.S. Census.

Usage

Building Advertising Market Outlook

The global building advertising market size was valued at approximately USD 12 billion in 2023 and is expected to reach around USD 22 billion by 2032, growing at a CAGR of 6.5% during the forecast period. The growth of the building advertising market is primarily driven by increasing urbanization, the proliferation of technological advancements, and the rising need for impactful advertisement mediums in densely populated urban areas.

One of the significant growth factors for the building advertising market is the rapid urbanization occurring worldwide. As cities expand and new buildings are constructed, there is an increasing number of surfaces available for advertising. This urban sprawl offers advertisers more opportunities to place their ads in high-traffic areas, garnering more visibility and engagement from potential consumers. Moreover, the rising population density in urban areas means that advertisers can reach a larger audience with a single advertisement placement, increasing the return on investment.

Technological advancements have also played a crucial role in the growth of the building advertising market. The advent of digital billboards and LED displays has revolutionized the way advertisements are presented, making them more dynamic, engaging, and customizable. These technologies allow for real-time updates and targeted advertising based on various factors such as time of day or demographic data. This level of customization ensures that advertisements are more relevant to the audience, thereby increasing their effectiveness.

Digital Buildings are transforming the landscape of urban advertising by integrating advanced technologies directly into the infrastructure of modern cities. These buildings are equipped with state-of-the-art digital displays that can showcase advertisements in a dynamic and engaging manner. By utilizing the facades of these buildings, advertisers can reach a vast audience with visually stunning content that captures attention and enhances brand visibility. The integration of digital technology into building architecture not only provides a platform for advertising but also contributes to the aesthetic appeal of urban environments, making cities more vibrant and interactive.

Another critical factor driving market growth is the increasing demand for impactful and memorable advertising mediums. Traditional forms of advertising such as TV and radio are becoming less effective as consumers are inundated with advertisements from multiple channels. Building advertising offers a unique and eye-catching alternative that can capture the attention of passersby in a way that traditional media cannot. This is particularly important in today's fast-paced world where consumers have shorter attention spans and are constantly bombarded with information.

Regionally, North America and Asia Pacific have been the leading markets for building advertising. North America, particularly the United States, has a mature market with well-established infrastructure and a high level of technological adoption. On the other hand, Asia Pacific is experiencing rapid growth due to increasing urbanization and economic development in countries like China and India. Europe also holds a significant share of the market, driven by its advanced technological landscape and high population density in urban areas. Latin America and the Middle East & Africa are expected to show moderate growth, with increasing investments in urban infrastructure and advertising capabilities.

Type Analysis

Digital billboards represent one of the fastest-growing segments within the building advertising market. These billboards are equipped with LED or LCD screens that can display dynamic and interactive content. The ability to change advertisements in real-time makes digital billboards highly versatile and effective. Advertisers can schedule multiple ads throughout the day, targeting different demographics and optimizing their campaigns based on real-time performance data. This flexibility is highly appealing to businesses looking to maximize their advertising budgets.

Traditional billboards, while not as technologically advanced as their digital counterparts, still hold a significant share of the market. These billboards offer a cost-effective way for brands to reach a broad audience. They are particularly effective in high-traffic areas such as highways and city centers where they ca

Nigeria has the largest population in Africa. As of 2025, the country counted over 237.5 million individuals, whereas Ethiopia, which ranked second, has around 135.5 million inhabitants. Egypt registered the largest population in North Africa, reaching nearly 118.4 million people. In terms of inhabitants per square kilometer, Nigeria only ranked seventh, while Mauritius had the highest population density on the whole African continent in 2023. The fastest-growing world region Africa is the second most populous continent in the world, after Asia. Nevertheless, Africa records the highest growth rate worldwide, with figures rising by over two percent every year. In some countries, such as Chad, South Sudan, Somalia, and the Central African Republic, the population increase peaks at over 3.4 percent. With so many births, Africa is also the youngest continent in the world. However, this coincides with a low life expectancy. African cities on the rise The last decades have seen high urbanization rates in Asia, mainly in China and India. African cities are also growing at large rates. Indeed, the continent has three megacities and is expected to add four more by 2050. Furthermore, Africa's fastest-growing cities are forecast to be Bujumbura, in Burundi, and Zinder, Nigeria, by 2035.
