Fig. 28. Status of the Population of the United States in 1900, in Regard to Marriage

This chart would have been improved if the figures had been given at the left end of the bars. Note that the four lower groups of bars are a cross-index of the information given in the upper group

Another application of the bar method is seen in Fig. 28. Each of the four lower groups of population is a subdivision of the total population shown in the upper group. The same data may be seen portrayed in a different way in Fig. 6. The arrangement of Fig. 6 is more desirable, in that the size of the components is more readily grasped when all are shown in the same horizontal bar. In Fig. 28 the eye does not readily make the addition necessary to fit together the four items "Single," "Married," "Widowed," and "Divorced" as percentages of the total 100 per cent in each group.
