Specific data on Macau is difficult to come by but based on the aggregate data for the Asia Pacific region and extrapolated results there are:
households (39.0%) with internet access at home
households (36.0%) with a computer
households (8.9%) with a fixed broadband subscription
households (42.3%) with an active mobile broadband subscription
(91.6%) mobile cellular telephone subscriptions
(11.3%) fixed telephone subscriptions
Macau is one of the countries which has higher total internet advertising growth but lower mobile internet penetration.
This means there is plenty of room for growth but mobile internet penetration will remain relatively low even in 2019 as smartphones are prohibitively expensive for a sizeable proportion of the population. Poor Internet infrastructure and slow adoption of fixed broadband slowed the early development of Internet advertising in many of these markets, but this is set to change as an emerging middle classes boosts consumption and economic growth increases advertising budgets.
