About this dataset

Context

The dataset tabulates the Perth population over the last 20 plus years. It lists the population for each year, along with the year on year change in population, as well as the change in percentage terms for each year. The dataset can be utilized to understand the population change of Perth across the last two decades. For example, using this dataset, we can identify if the population is declining or increasing. If there is a change, when the population peaked, or if it is still growing and has not reached its peak. We can also compare the trend with the overall trend of United States population over the same period of time.

Key observations

In 2022, the population of Perth was 6, a 0.00% decrease year-by-year from 2021. Previously, in 2021, Perth population was 6, a decline of 0.00% compared to a population of 6 in 2020. Over the last 20 plus years, between 2000 and 2022, population of Perth decreased by 7. In this period, the peak population was 13 in the year 2000. The numbers suggest that the population has already reached its peak and is showing a trend of decline. Source: U.S. Census Bureau Population Estimates Program (PEP).

The statistic depicts Australia's gross domestic product (GDP) from 1987 to 2024, with projections up until 2030. In 2024, GDP in Australia amounted to about 1.8 trillion US dollars. See global GDP for a global comparison. Australia’s economy and population Australia’s gross domestic product has been growing steadily, and all in all, Australia and its economic key factors show a well-set country. Australia is among the countries with the largest gross domestic product / GDP worldwide, and thus one of the largest economies. It was one of the few countries not severely stricken by the 2008 financial crisis; its unemployment rate, inflation rate and trade balance, for example, were hardly affected at all. In fact, the trade balance of Australia – a country’s exports minus its imports – has been higher than ever since 2010, with a slight dip in 2012. Australia mainly exports wine and agricultural products to countries like China, Japan or South Korea. One of Australia’s largest industries is tourism, which contributes a significant share to its gross domestic product. Almost half of approximately 23 million Australian residents are employed nowadays, life expectancy is increasing, and the fertility rate (the number of children born per woman) has been quite stable. A look at the distribution of the world population by continent shows that Australia is ranked last in terms of population and population density. Most of Australia's population lives at the coast in metropolitan areas, since parts of the continent are uninhabitable. Unsurprisingly, Australia is known as a country with very high living standards, four of its biggest cities – Melbourne, Adelaide, Sydney and Perth – are among the most livable cities worldwide.

The Australian Marine Microbial Biodiversity Initiative (AMMBI) provides methodologically standardized, continental scale, temporal phylogenetic amplicon sequencing data describing Bacteria, Archaea and microbial Eukarya assemblages. Sequence data is linked to extensive physical, biological and chemical oceanographic contextual information. Samples are collected monthly to seasonally from multiple depths at seven National Reference Stations (NRS) sites: Darwin Harbour (Northern Territory), Yongala (Queensland), North Stradbroke Island (Queensland), Port Hacking (New South Wales), Maria Island (Tasmania), Kangaroo Island (South Australia), Rottnest Island (Western Australia). The Integrated Marine Observing System (IMOS) NRS network is described at http://imos.org.au/facilities/nationalmooringnetwork/nrs/ Rottnest Island NRS is located 18 nm offshore and 2.5 nm from Rottnest Island, at a depth of 50 m over sand but surrounded by low relief limestone reef which is predominately covered with macro-algae, mainly Ecklonia spp, on the Western Australia coast, near Perth (population 1.83 million). This is the only NRS situated on the Indian Ocean coastline. This station is heavily impacted by the Leuwin Current (LC), which delivers warm but less saline waters southward. The LC is strongly affected by ENSO and IOD events. The prevailing winds and current direction leads to coastal suppression of upwelling along the Western Australian coast throughout most of the year, and consequently sea surface temperatures of up to 4–5?°C warmer than upwelling systems at similar latitudes elsewhere on the globe2. There is an historical oceanographic dataset from this site (with intermittent gaps in certain parameters) dating back to 1951.

The Australian commercial real estate market, valued at $34.07 billion in 2025, is projected to experience robust growth, exhibiting a Compound Annual Growth Rate (CAGR) of 8.46% from 2025 to 2033. This expansion is fueled by several key drivers. Strong population growth in major cities like Sydney, Melbourne, and Brisbane is increasing demand for office, retail, and industrial spaces. Furthermore, the burgeoning e-commerce sector is driving significant growth in the logistics and warehousing segments. Government infrastructure investments and a generally positive economic outlook also contribute to this positive market trajectory. While rising interest rates and potential economic slowdown pose some constraints, the long-term fundamentals of the Australian economy and the ongoing need for modern commercial spaces are expected to mitigate these risks. The market is segmented by property type (office, retail, industrial & logistics, hospitality, and others) and by city (Sydney, Melbourne, Brisbane, Adelaide, Canberra, Perth), reflecting diverse investment opportunities and regional variations in growth rates. Sydney and Melbourne are expected to remain dominant, given their established business ecosystems and high population densities. However, other cities such as Brisbane are witnessing significant growth driven by infrastructure development and population influx. The key players in this dynamic market, including Lendlease Corporation, Scentre Group Limited, and Mirvac, are well-positioned to capitalize on these growth opportunities. The segmentation of the market reveals significant potential within specific sectors. The industrial and logistics sector, driven by the e-commerce boom and supply chain optimization efforts, is anticipated to experience particularly strong growth. Similarly, the office sector, while facing some challenges from remote work trends, remains resilient due to the ongoing need for collaborative workspaces and central business district locations. The retail sector will continue to adapt to evolving consumer preferences, with a focus on experience-driven retail and omnichannel strategies. Careful consideration of factors like interest rate fluctuations, construction costs, and regulatory changes will be crucial for investors navigating the complexities of this dynamic market. The forecast period of 2025-2033 offers a promising outlook for sustained growth within this sector. Recent developments include: • October 2023: Costco is planning a major expansion in Australia, with several new warehouses under construction and several prime locations being considered for future locations. Costco currently operates 15 warehouses in Australia, with plans to expand to 20 within the next five years, based on current stores and potential locations., • July 2023: A 45-storey BTR tower will be developed by Lendlease and Japanese developer Daiwa House, completing the final phase of Lendlease's Melbourne Quarter project and its second Build-to-Rent (BTR) project in Australia. The USD 650 million deal, similar to Lend lease's first 443-unit BTR project under construction in the 5.5 hectares of mixed-use space at Brisbane Showground, is a stand-alone investment and is separate from the company's ongoing efforts to build a wider BTR partnership, which will include several assets.. Key drivers for this market are: Rapid Urbanization, Government Initiatives Actively promoting the Construction Activities. Potential restraints include: Rapid Urbanization, Government Initiatives Actively promoting the Construction Activities. Notable trends are: Retail real estate is expected to drive the market.

The groundwater resource contained within the sandy aquifers of the Swan Coastal Plain, south-west Western Australia, provides approximately 60 percent of the drinking water for the metropolitan population of Perth. Rainfall decline over the past three decades coupled with increasing water demand from a growing population has resulted in falling dam storage and groundwater levels. Projected future changes in climate across south-west Western Australia consistently show a decline in annual rainfall of between 5 and 15 percent. There is expected to be a reduction of diffuse recharge across the Swan Coastal Plain. This study aims to quantify the change in groundwater recharge in response to a range of future climate and land cover patterns across south-west Western Australia. Modelling the impact on the groundwater resource of potential climate change was achieved with a dynamically linked unsaturated/saturated groundwater model. A vertical flux manager was used in the unsaturated zone to estimate groundwater recharge using a variety of simple and complex models based on climate, land cover type (e. g. native trees, plantation, cropping, urban, wetland), soil type, and taking into account the groundwater depth. In the area centred on the city of Perth, Western Australia, the patterns of recharge change and groundwater level change are not consistent spatially, or consistently downward. In areas with land-use change, recharge rates have increased. Where rainfall has declined sufficiently, recharge rates are decreasing, and where compensating factors combine, there is little change to recharge. In the southwestern part of the study area, the patterns of groundwater recharge are dictated primarily by soil, geology and land cover. In the sand-dominated areas, there is little response to future climate change, because groundwater levels are shallow and much rainfall is rejected recharge. Where the combination of native vegetation and clayey surface soils restricts possible infiltration, recharge rates are very sensitive to reductions in rainfall. In the northern part of the study area, both climate and land cover strongly influence recharge rates. Recharge under native vegetation is minimal and is relatively higher where grazing and pasture systems have been introduced after clearing of native vegetation. In some areas, the recharge values can be reduced to almost zero, even under dryland agriculture, if the future climate becomes very dry.
