Basic Cross-Section and Time Series Analyses of the Average Per Capita Expenditure (ACE) and Average Household Expenditure (AHE) of the Mining Sector from 1988-2009 (in 2009 prices)

During one of our meetings, we were tasked to observe a certain data set about the different sectors in our society. I was assigned to analyze the average per capita expenditure and average household expenditure of the mining sector from 1988-2009 (in 2009 prices).

Time series analysis of the Average Per Capita Expenditure show an increase, however in small amounts, (the year 1994 being the highest increase which was about 24.54%), from the years 1988-2000. It is quite noticeable that the mining expenditure increase in 1997 to 2000 was only a meager 0.81%- which was followed by a 7.71% decrease from 2000 to 2003. ACE followed a decreasing trend (in large increments) from that year on. The ACE in the mining sector also never left the 100 000 margin, in contrast with all the other sectors whose prices fluctuated immensely. It is also worth noting how almost all the other sectors also exhibited a decrease in expenditure from the year 2000. For the cross section analysis of the ACE, the mining sector is one of the lowest among all the other sectors, it being second to the last from the years 1988-2009 except in 1994 for which it placed third to the last with its expenditure amounting to 168, 768, which was also the mining’s sectors’ peak in expenditure. For the year 1988, it spent 127, 396 only behind by a pinch from the construction sector whose expenses amounted to 129, 024. For the following years, the mining sector maintained a low expenditure relative to the other sectors. Throughout the years, the finance sector had the highest amount of per capita expenditure, and the agricultural sector consistently held the least.

The time series analysis of the Average Household Expenditure also show an increasing trend from the years 1988-2000 and then a decrease from the years 2000-2009. Just like in the per capita expenditure, the increases were in small amounts, the 1991-1994 increase being the highest which is about 24.53%. The increase in the years 1997-2000 was also just like the ACE, which was only 0.81%. The AHE followed a decreasing trend from that year on as well. For the cross section analysis of the AHE, the mining sector is also one of the lowest among all the other sectors, it being second to the last from the years 1988-2009, except in the year 1994, where it placed third to the last with its expenditure amounting to 168, 768. The mining sector also reached its peak in AHE this year. The finance and agricultural sectors, just like in the ACE, consistently held the greatest and least amounts of expenditure from 1988-2009, respectively.

  1. It is interesting to see that the mining sector contributes so little to both the country’s GDP and welfare and still continue to expand their operations.
