Aging of the U.S.and world populations highlights the need to understand how and where people age successfully.Older adults with chronic conditions may rate themselves subjectively as aging successfully despite their objective limitations.A typology of successful aging combining objective and subjective criteria has been tested,but spatial patterns in these dimensions have not been widely studied.Our research explores patterns of successful and unsuccessful aging using the colocation quotient,a measure of spatial association among categories in a population.The colocation quotient assesses the degree to which older adults who age successfully are likely to live near other adults who do not age successfully. Data on5576participants in the ORANJ BOWL SM survey,a statewide survey of older adults in New Jersey, were geocoded to the Census block level.Each participant was scored as aging successfully or not on each of the two dimensions.Global and local patterns of colocation of successful and unsuccessful aging in individuals were calculated based on the objective and subjective measures separately and then compared.The analysis reveals a strong regional pattern.In northern New Jersey and along the southeast coast,successful older adults on both dimensions were more likely to be colocated with subjectively unsuccessful older adults.In southern New Jersey,especially in the southwest,successful older adults on both dimensions were more likely to be colocated with the objectively unsuccessful.Spatial analysis of colocation can inform needs assessment for the growing population of older adults by identifying where older people age successfully and where they are aging unsuccessfully.

Introduction

Older Americans numbered41.4million in2011,more than13% of the U.S.population(Administration on Aging,2012).Over the next30years,the number of people65or older is expected to double,accounting for20%of the total population.Similar de-mographic shifts are occurring in other countries(United Nations, Department of Economic and Social Affairs,Population Division,2013).Although population aging is a global concern,patterns and processes of aging vary from country to country and within countries(Davies&James,2011),highlighting the need to under-stand how and where people age successfully.Spatial analysis of colocation can inform needs assessment for the growing popula-tion of older adults by identifying where older people age suc-cessfully and where they are aging unsuccessfully at the regional and local levels.

The concept of successful aging has a long history.Cicero,in his treatise De Senectute,grappled with the extent to which later life could be a time of vitality and activity.Gerontologists have strug-gled to de?ne,measure,and predict successful aging for more than half a century(Cumming&Henry,1961;Havighurst,1963;Palmore, 1979).

The groundbreaking work of Rowe and Kahn(1987,1998) proposed that people aging successfully would show little or no
