Chart and table of population level and growth rate for the Portland metro area from 1950 to 2025.

This data layer is an element of the Oregon GIS Framework. The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation.

Census tracts are small, relatively permanent statistical subdivisions of a county or equivalent entity, and were defined by local participants as part of the 2020 Census Participant Statistical Areas Program. The Census Bureau delineated the census tracts in situations where no local participant existed or where all the potential participants declined to participate. The primary purpose of census tracts is to provide a stable set of geographic units for the presentation of census data and comparison back to previous decennial censuses. Census tracts generally have a population size between 1,200 and 8,000 people, with an optimum size of 4,000 people. When first delineated, census tracts were designed to be homogeneous with respect to population characteristics, economic status, and living conditions. The spatial size of census tracts varies widely depending on the density of settlement. Physical changes in street patterns caused by highway construction, new development, and so forth, may require boundary revisions. In addition, census tracts occasionally are split due to population growth, or combined as a result of substantial population decline. Census tract boundaries generally follow visible and identifiable features. They may follow legal boundaries such as minor civil division (MCD) or incorporated place boundaries in some States and situations to allow for census tract-to-governmental unit relationships where the governmental boundaries tend to remain unchanged between censuses. State and county boundaries always are census tract boundaries in the standard census geographic hierarchy. In a few rare instances, a census tract may consist of noncontiguous areas. These noncontiguous areas may occur where the census tracts are coextensive with all or parts of legal entities that are themselves noncontiguous. For the 2010 Census and beyond, the census tract code range of 9400 through 9499 was enforced for census tracts that include a majority American Indian population according to Census 2000 data and/or their area was primarily covered by federally recognized American Indian reservations and/or off-reservation trust lands; the code range 9800 through 9899 was enforced for those census tracts that contained little or no population and represented a relatively large special land use area such as a National Park, military installation, or a business/industrial park; and the code range 9900 through 9998 was enforced for those census tracts that contained only water area, no land area.

PARD’s Long Range Plan for Land, Facilities and Programs, Our Parks, Our Future (adopted November 2019) compared Austin’s park system to five peer cities: Atlanta, GA, Dallas, TX, Portland, OR, San Antonio, TX, and San Diego, CA. The peer cities were selected based on characteristics such as population, size, density, and governance type. Portland and San Diego were selected as aspirational cities known for their park systems.

Cement Clinker and Cement Market Outlook

The global cement clinker and cement market size was valued at approximately $348 billion in 2023 and is projected to reach about $518 billion by 2032, growing at a compound annual growth rate (CAGR) of 4.6% during the forecast period. The growth in this market is majorly driven by the rapid urbanization and industrialization occurring globally. As developing countries continue to expand their infrastructure and residential projects, the demand for cement and clinker is expected to rise significantly.

One of the primary growth factors in the cement clinker and cement market is the unprecedented urbanization rates witnessed across the globe. Urban areas are expanding at a phenomenal pace, particularly in emerging economies such as India, China, and Brazil. These expansions necessitate robust infrastructure development, including residential complexes, commercial buildings, and public infrastructure like roads, bridges, and airports, thereby driving cement consumption. Additionally, government initiatives to improve public infrastructure in various countries further supplement this growth.

Industrialization is another crucial factor propelling the market. As countries aim to boost their economic output and global competitiveness, they are investing heavily in industrial projects. These projects require a substantial amount of high-quality cement and clinker for constructing factories, warehouses, and other industrial facilities. Moreover, the shift towards sustainable and energy-efficient building practices is encouraging the use of innovative cement types, which are less harmful to the environment and offer superior durability.

The rise in residential construction activities, driven by increasing urban migration and population growth, is significantly contributing to the market's expansion. Governments and private entities are investing in affordable housing projects to accommodate the growing urban population. This trend is particularly strong in regions such as Asia-Pacific and Africa, where population growth rates are among the highest globally. The increasing need for housing fuels the demand for various types of cement and clinker, making it a critical component of the market's growth.

Regionally, Asia-Pacific dominates the cement clinker and cement market, accounting for the largest share. The region's substantial market size is attributed to its high population density, rapid urbanization, and extensive infrastructure development. Countries such as China and India lead the region with significant investments in both residential and commercial construction. North America and Europe also contribute a considerable share to the market, albeit at a slower growth rate due to mature markets. The Middle East & Africa region is expected to witness significant growth, driven by infrastructural developments and economic diversification efforts.

Product Type Analysis

The cement clinker and cement market can be segmented by product type into Portland cement, white cement, clinker, and others. Portland cement, being the most widely used type, holds the largest market share. It is preferred for its strength and durability, making it suitable for a variety of construction purposes ranging from residential buildings to large-scale infrastructure projects. The versatility and cost-effectiveness of Portland cement make it a staple in the construction industry.

White cement, although less commonly used than Portland cement, occupies a unique niche in the market. It is primarily used for decorative purposes due to its aesthetic appeal. White cement is often employed in architectural projects where appearance is a crucial consideration, such as facades, tiles, and ornamental concrete products. The higher cost of white cement compared to other types limits its usage to specific applications, but its demand is growing in regions with a high focus on architectural design and aesthetics.

Clinker, a key component in the production of cement, is also a significant segment within the market. Clinker is produced by heating limestone and other materials in a kiln at high temperatures, resulting in a hard, nodular material. It is then ground with gypsum to produce cement. The demand for clinker is directly tied to cement production levels, and its market is driven by the overall growth in the construction industr
