On the Decline: A Look at Earth’s Biodiversity Loss, By Region

The Briefing

  • The Living Planet Index (LPI) tracks the abundance of mammals, birds, fish, reptiles, and amphibians across the globe
  • Between 1970 and 2016, the average decline in vertebrate populations was 68%, but the rate of loss differs from region to region
  • Latin America & Caribbean has seen the largest drop in biodiversity at 94%

Visualizing the Decline of Earth’s Biodiversity, By Region

Earth’s biodiversity has seen an overall decrease across the globe. And while each region has seen a decline, some places have experienced higher drops than others.

Using data from WWF’s Living Planet Report 2020, we’ve ranked each region from the greatest average loss in biodiversity, to the least:

RankRegionAverage decline (between 1970 and 2016)
1Latin America & Caribbean94%
2Africa65%
3Asia Pacific45%
4North America33%
5Europe and Central Asia24%

Latin America and Caribbean has seen the most loss, with a 94% drop in average species populations, while Africa comes in second with a 65% drop.

The 5 Major Threats for Biodiversity Loss

While the rate of loss varies across regions, WWF has identified five major threats that are linked to drops in species populations across all regions:

  • Changes in land-use and sea use
    This threat refers to any changes in a species habitat, caused by mining, development, unsustainable agriculture, etc.
  • Species overexploitation
    There are two types of species overexploitation—direct and indirect. Direct is when a species is intentionally hunted. Indirect happens when a species is unintentionally killed (an example would be by-catch in fisheries).
  • Invasive species and disease
    This threat impacts species populations in several ways. Invasive species may spread diseases or may become predators to native species that are not equipped to defend themselves.
  • Pollution
    Pollutants can have both gradual and instant effects on a species. For example, an oil spill has an instant effect on a species’ environment. But other pollutants, such as microplastics, have a much more gradual impact on species health.
  • Climate Change
    This threat has an indirect impact on species. Changes in temperature as a result of climate change can trigger irregular season changes, which can affect natural phenomena like migration and mating seasons.

Ranked: These Are 10 of the World’s Least Affordable Housing Markets

An analysis of 90+ major cities reveals which ones are the least affordable housing markets based on their price-to-income ratio.

Published

on

The Briefing

  • For the 12th year in a row, Hong Kong is the world’s least affordable housing market, according to Demographia’s ranking of 92 cities in select countries
  • Sydney, Australia moves up one spot from last year’s ranking to take second place

These Are 10 of the World’s Least Affordable Housing Markets

It’s become increasingly difficult for middle-class families to purchase a home over the last few years—and the global pandemic has only made things worse.

According to Demographia’s 2022 Housing Affordability Report, the number of housing markets around the world deemed “severely unaffordable” increased by 60% compared to 2019 (prior to the pandemic).

This graphic looks at some of the least affordable housing markets across the globe, relative to median household income. The report covers 92 different cities in eight nations: Australia, Canada, China, Ireland, New Zealand, Singapore, the United Kingdom, and the United States.

The Least Affordable Housing Markets

Before diving in, it’s worth outlining the methodology used in this report, to help explain what’s classified as a severely unaffordable housing market.

To calculate affordability, a city’s median housing price and divided by its median household income. From there, a city is given a score:

  • A score of 5.1 or above is considered severely unaffordable
  • 4.1 to 5.0 is considered seriously unaffordable
  • 3.1 to 4.0 is considered moderately unaffordable

All the cities on this graphic are classified as severely unaffordable⁠—and, for the 12th year in a row, Hong Kong takes the top spot as the world’s most unaffordable housing market, with a score of 23.2.

Housing MarketNationScore
Hong Kong🇭🇰​ Hong Kong (SAR)23.2
Sydney, NSW🇦🇺​ Australia15.3
Vancouver, BC🇨🇦​ Canada13.3
San Jose, CA🇺🇸​ U.S.12.6
Melbourne, VIC🇦🇺​ Australia12.1
Honolulu, HI🇺🇸​ U.S.12.0
San Francisco, CA🇺🇸​ U.S.11.8
Auckland, AUK🇳🇿​ New Zealand11.2
Los Angeles, CA🇺🇸​ U.S.10.7
Toronto, ON🇨🇦​ Canada10.5

One reason for Hong Kong’s steep housing costs is its lack of supply, partly due to its lack of residential zoning—which only accounts for 7% of the region’s zoned land. For context, 75% of New York City’s land area is dedicated to residential housing.

Sydney moved up one spot this year, making it the second most expensive city to purchase a home on the list, with a score of 15.3. Besides Hong Kong, no other city has scored this high in the last 18 years this report has been released.

There are several theories for Sydney’s soaring housing rates, but industry expert Tom Forrest, CEO of Urban Taskforce Australia, boils it down to one fundamental issue in an interview with Australia Broker—supply isn’t keeping up with demand:

“Housing supply has been consistently not meeting demand in the Greater Sydney and across regional New South Wales…if you have supply consistently not meeting demand then the price will go up. That’s what happened and we’re seeing it in abundance.”Tom Forrest, CEO of Urban Taskforce Australia

The COVID-19 Impact

Middle-income earners were already feeling the squeeze prior to the global pandemic, but COVID-19 only exacerbated housing affordability issues.

As people began to work from home, high-income earners started to look for more spacious housing that wasn’t necessarily in the city center, driving up demand in suburban areas that were relatively affordable prior to the pandemic.

At the same time, supply chain issues and material costs impacted construction, which created a perfect storm that ultimately drove housing prices up.

But with interest rates rising and COVID-19 restrictions easing around the world, some experts are predicting a market cool down this year—at least in some parts of the world.

Poll: Inflation is the Top Financial Concern for Americans

Many Americans are feeling the sting of inflation as everyday items like food and fuel have seen big price increases.

The Briefing

  • Inflation has quickly become the top financial concern for American families
  • Compared to 2021, far fewer Americans believe their financial situation is improving

Poll: Inflation is the Top Financial Concern for Americans

A recent survey by Gallup discovered that inflation has become the top financial concern for Americans, surpassing other issues like low wages and housing costs.

While this result may not be too surprising, it is interesting to see how today’s concerns compare to that of previous years. For reference, the Consumer Price Index (CPI) has grown 8.3% between April 2021 and April 2022, representing a near 40-year high.

Poll Results

Results were collected in April 2022 and are based on the responses of over 1,000 U.S. adults. In this case, the specific question was: What is the most important financial problem facing your family today?

TrendApril 2022April 2021April 2020April 2019
Inflation32%8%3%6%
Low wages11%10%11%11%
Gas prices10%1%----
Housing costs8%9%9%8%
Health care costs7%8%8%17%

Percentage of respondents. Includes the top five categories, based on April 2022 results.

Based on these results, we can see that inflation began to gain momentum in early 2021. Rising gas prices, which are a significant contributor to overall inflation, also popped up in 2021.

Implications

Significantly fewer Americans feel confident about their financial situation due to the rising cost of living. This was captured in the same Gallup survey referenced above.

Income Group20222021Percentage point decrease
Upper 50%28%-22
Middle48%39%-9
Lower63%45%-18

Percentage of respondents who say their personal financial situation is improving.

The largest decreases were seen among the upper and lower income groups.

Upper income families tend to own more financial assets like stocks and bonds. An inflationary environment, especially when combined with rising interest rates, can eat away at the returns generated by these assets, which could explain this cohort’s drop in optimism.

Lower income families, on the other hand, are more likely to be struggling already. In fact, a 2017 report found that six in 10 Americans don’t have $500 in savings. With this in mind, it’s easy to see how an increase in the price of food or gas could cause worry.
