Recent developments in agriculture have meant that since the 1960s, unemployment has fallen from over 60% to under 10% in the early 2000s. In the same period: food prices halved, hunger decreased (from 2.55 million households in 1988 to 418,000 in 2007) and child malnutrition have greatly reduced (from 17% in 1987 to 7% in 2006). This has been achieved through a mixture of a strong and positive state role in ensuring investment in infrastructure, education and access to credit and successful private initiatives in the agribusiness sector. This has supported Thailand's transition to an industrialised economy.
