identify the words that indicate DIFFERENCES between elements (here, differences between household income per province). According to politicsweb.co.za, households in Gauteng and the Western Cape earn the highest income per year. In contrast, households in the Eastern Cape and Limpopo earn the lowest income. It is generally believed that a large number of people living in South Africa move to the cities in search of better job opportunities in the urban areas. Since Johannesburg and Cape Town both have well-established and strong economies, they tend to offer more opportunities for better employment. This has however left rural provinces such as the Eastern Cape and Limpopo with a reduced workforce. It can also be seen that the average household income has more than doubled in all provinces in the past 10 years. This may be in part due to the improved South African economy, as well as an increase in inflation.
