Abstract:
Older Americans rely heavily on Social Security benefits (SSBs) to support independent lifestyles, and many have few or no additional sources of income. We establish the extent to which SSBs adequately support economic security, benchmarked by the Elder Economic Security Standard Index. We document variability across U.S. counties in the adequacy levels of SSBs among older adults. We find that the average SSBs fall short of what is required for economic security in every county in the United States, but the level of shortfall varies considerably by location. Policy implications relating to strengthening Social Security and other forms of retirement income are discussed.

Titration Calculations: Strong Acid - Strong Base
A titration is carried out for 25.00 mL of 0.100 M HCl (strong acid) with 0.100 M of a strong base NaOH. The pH at different volumes of added base solution can be calculated as follows:
(a) Titrant volume = 0 mL. The solution pH is due to the acid ionization of HCl. Because this is a strong acid, the ionization is complete and the hydronium ion molarity is 0.100 M. The pH of the solution is then:
