Overall living conditions in Singapore on a slump

But it still secured the top spot in global liveability rankings.

Singapore remains the world's most liveable location for Asian expatriates, according to the latest Location Rankings by ECA International.

However, in terms of overall living conditions, Singapore has, for the past five years, deteriorated compared to other regional neighbours including Japan and Australia.

“We have witnessed a gradual decline in Singapore’s overall quality of living in the past five years due to the deteriorating air pollution situation here, whilst cities such as Brisbane, Sydney, and Osaka have all improved in terms of their overall liveability,” said ECA International regional director for Asia Lee Quane.

It's no different with Singapore's rival Hong Kong, which has fallen to 29th position in the global rankings and remains the 15th most liveable location in the Asia Pacific region for Asian expatriates.

For the past five years, there has been a gradual decline in Hong Kong's global and regional ranking, leading to the worsening gap between the territory and Singapore.

“Environmental factors such as lower levels of air pollution and the fact that Singapore is spared the impact of natural disasters such as typhoons that afflict Hong Kong annually are also key contributors,” noted Quane.
