The role of data entry clerks working with physical hand-written documents is on the decline in the developed world, because employees within a company frequently enter their own data, as it is collected now, instead of having a different employee do this task. An example of this is an operator working in a call center or a cashier in a shop. Cost is another reason for the decline. Data entry is labor-intensive for large batches and, therefore, expensive, so large companies will sometimes outsource the work, either locally or to third world countries where there is no shortage of cheaper unskilled labor.
