a reflection of the decline in birth rates in the 

 1960's. By 2000, however, projected housing 

 demand rises again to about 2.8 million units. 

 The high and low projections follow similar 

 trends. 



The projections of housing demand in the 1970's 

 used in this study are somewhat below National 



housing goals. 19 Differences between these goals 

 and the high projection of this study, for example, 

 amount to 0.8 million units over the 1973-78 

 period.
