The given line graphs illustrate the production and actual needs of steel in million tonnes in the UK for the year 2010 and the number of labourers involved in thousands for its manufacturing in the same year.
Overall, steel produced in UK was relatively higher than actual demand over the whole year except the month of December. Whereas, the data of workers was significantly declined by the end of the year.With regard to demand and supply of steel, both of them showed increasing trend in January. Production started from 4000 million tonnes to reach 5000 million tonnes in the initial months , that is a 25% rise , while demand was increasing but slowly to reach a value of 3000 million tonnes by March. Thereafter, the production remained steady at 4000 million tonnes until the end of July and then sharply declined at the end of the year to 1000 million tonnes before fluctuating in between. While, the demand for steel suddenly dropped to nil in November, before regaining demand next month.
The number of labourers employed in steel manufacturing had a decreasing trend starting form 5000 in the start of the year. The data showed significant decrease in march from 5500 to 3000, thereafter fluctuating around 3000 for next 6 months before dropping to 1000 in December.
