group accounts for 23.6 percent of the entire world-wide amount.

Housing

and community facilities make up 21.2 percent of the world-wide total; in foreign countries this group comprises 25.8 percent of the foreign countries total.

Table 10 shows the ten categories of real property, listed in order of cost, in which the Department of Defense has the largest dollar investment. These data are illustrated in Chart 4. The ten categories on a world-wide basis represent a total cost of $24.5 billion or nearly two-thirds (63.9 percent) of the cost of all Defense-controlled real property.

Family housing is the largest single category followed by airfield pavements and troop housing; each of these three groups has acquisition cost of over $3 billion. As of 30 June 1966, the cost of family housing inventory was nearly $3.5 billion, about $102 million more than the amount one year earlier. World-wide inventory of airfield pavements increased $25 million to $3.1 billion. The troop housing world-wide total was $36 million more than for one year earlier.

Comparable data on the ten largest categories within the United States are presented for each of the military departments in Tables 21 (Army), 25 (Navy), and 29 (Air Force).

The cost of land controlled by the Department of Defense represents only 1.8 percent of the total cost of all real property controlled by the Department of Defense. Cost of buildings, on the other hand, represents 54.9 percent of the total costs of military real property controlled. Other improvements not classified as buildings such as

airfield pavements, communication towers, utility systems, operational and test structures, and roads and streets account for 43.3 percent. Table 11 shows the cost of buildings by broad geographical areas and by military department.

The over-all inventory cost of buildings, world

wide is $21.1 billion as compared with $20.5 billion one year earlier. Of the total world-wide increase in inventory of $832 million during the year ended 30 June 1966, $563 million or 68 percent was in properties classified as buildings. From Table 11, it may be noted that about one

half of the Navy and Air Force properties are classified as buildings,

on a dollar basis; for Army about two-thirds of the properties are classifie

as buildings.

Lease Rentals The total world-wide annual rental bill paid for properties used by the Department of Defense on the basis of leases in effect on 30 June 1966 was $58.65 million as compared with $34.99 million a year earlier. A small overall decrease of $109 thousand in Air Force rentals paid occurred whereas sizeable increases of $900 thousand for the Navy and $22.8 million for the Army were recorded.

The more than

doubled amount of rentals paid by the Army were for properties acquired in foreign countries.

Table 12 shows annual rentals paid.

Offsetting in part the $58.65 million paid out in rentals were receipts of $8.71 million for properties leased to others on the basis of leases in effect at the end of the year (see Table 13). The bulk (97 percent) of rental receipts was for properties in the United States.

About 51

percent of total receipts were from Army, 34 percent from Navy, and 15 percent from Air Force properties leased to others.
