Abstract
The development of the construction industry is affected by economic and political instability; there is virtually no research conducted to measure the Construction Industry (CI) development in Yemen. Therefore, this research investigates the behaviour of construction costs for more than two decades, then compare the construction industry development in Yemen with some low-income developing countries. Due to this lack of construction statistical data and researches, a simple Construction Industry Sustainable Development Indicator (CISDI) is developed to assess and monitor the local construction sector development in Yemen and compare then it with similar low-income developing countries. The increase in CISDI values through the last years showed that the CI development in Yemen is facing development problems. The result suggest that the values obtained from this indicator provide a reasonable measure for construction development.
