Malaysia's recent rapid development has attracted millions of migrant workers from across Asia. The majority of these migrants are undocumented, a situation which the Malaysian government is struggling to combat, with its treatment and crackdown on migrant workers often criticised by international human rights watchdogs. Malaysia has a newly industrialised market economy, ranked 4th largest in Southeast Asia and 38th largest in the world. With a GDP per capita of $10,430 and an HDI of 0.789, Malaysia is classified as an emerging economy by the World Bank. The International Monetary Fund (IMF) also classifies Malaysia as an emerging and developing country. Malaysia is a founding member of the Association of Southeast Asian Nations, the East Asia Summit, and the Organisation of Islamic Cooperation and a member of the APEC.

Malaysia's road network is one of the most comprehensive in Asia and covers a total of 144,403 kilometres (89,728 mi). The main national road network is the Malaysian Federal Roads System, which span over 49,935 km (31,028 mi). Most of the federal roads in Malaysia are 2-lane roads. In town areas, federal roads may become 4-lane roads to increase traffic capacity. Nearly all federal roads are paved with tarmac except parts of the Skudai Pontian-Highway which is paved with concrete, while parts of the Federal Highway linking Klang to Kuala Lumpur, is paved with asphalt. Malaysia has over 1,798 kilometres (1,117 mi) of highways and the longest highway, the North-South Expressway, extends over 800 kilometres (497 mi) on the West Coast of Peninsular Malaysia, connecting major urban centres like Kuala Lumpur, Penang and Johor Bahru. In 2015, the government announced a RM27 billion (USD 8.23 billion) Pan-Borneo Highway project to upgrade all trunk roads to dual carriage expressways, bringing the standard of East Malaysian highways to the same level of quality of Peninsular highways.

The education system features a non-compulsory kindergarten education followed by six years of compulsory primary education, and five years of optional secondary education. Schools in the primary education system are divided into two categories: national primary schools, which teach in Malay, and vernacular schools, which teach in Chinese or Tamil. Secondary education is conducted for five years. In the final year of secondary education, students sit for the Malaysian Certificate of Education examination. Since the introduction of the matriculation programme in 1999, students who completed the 12-month programme in matriculation colleges can enroll in local universities. However, in the matriculation system, only 10 per cent of places are open to non-bumiputera students.

Around these two halves of Malaysia are numerous islands, the largest of which is Banggi. The local climate is equatorial and characterised by the annual southwest (April to October) and northeast (October to February) monsoons. The temperature is moderated by the presence of the surrounding oceans. Humidity is usually high, and the average annual rainfall is 250 cm (98 in). The climates of the Peninsula and the East differ, as the climate on the peninsula is directly affected by wind from the mainland, as opposed to the more maritime weather of the East. Local climates can be divided into three regions, highland, lowland, and coastal. Climate change is likely to affect sea levels and rainfall, increasing flood risks and leading to droughts.
