During each of the three years the building trades had the largest number of strikes. As regards the number of persons affected, the building trades had the largest number in 1901, the mining industry had the largest number in 1902, and the transportation industry had the largest number in 1903.

The table which follows shows the number of strikes, establishments involved, and persons affected each year, classified by causes. For the year 1901 the strike is taken as the unit. For the years 1902 and 1903, however, the cause is taken as the unit, so that wherever a strike was due to two or more causes the data for such a strike are repeated under each cause. Hence the total number of strikes, establishments involved, and persons affected in 1902 and 1903, as shown in the tables giving causes of strikes, does not agree with the number in the other tabies.

CAUSES OF STRIKES, 1901 TO 1903.

As

[For the year 1901 the strike, and for the years 1902 and 1903 the cause, has been taken as the unit. a considerable number of strikes in 1902 and 1903 were due to two or more causes, the facts in those cases have been tabulated under each cause; hence the totals for those years do not agree with those in other tables.]

It will be observed that the strikes in each year were mostly due to wage disputes, strikes for the reinstatement of employees being next in importance.

The results of strikes are shown in the following table:

The proportion of strikes which succeeded shows a decrease each year, while the proportion which succeeded partly and which failed shows an increase.

In the table which follows the strikes are shown, by causes and results, for each of the three years, 1901, 1902, and 1903. As in a preceding table, the strike is taken as the unit in 1901 and the cause as the unit in 1902 and 1903:

STRIKES, BY CAUSES AND RESULTS, 1901 TO 1903.

[For the year 1901 the strike, and for the years 1902 and 1903 the cause, has been taken as the unit. As a considerable number of strikes in 1902 and 1903 were due to two or more causes, the facts in those cases have been tabulated under each cause; hence the totals for those years do not agree with those in other tables.]

The next table shows the strikes in 1901, 1902, and 1903 by duration and results:

STRIKES, BY DURATION AND RESULT, 1901 TO 1903.

More than one-half of the strikes for which duration was reported lasted 7 days or less, and but 8 strikes during the three years lasted over 91 days.

The table which follows shows the number of strikes and their results, and the number of persons affected by strikes, classified according to method of settlement:

STRIKES, BY METHOD OF SETTLEMENT, 1901 TO 1903.

a By disintegration is meant the breaking up of the strike by the gradual return of the strikers.
