In collaboration with the Department of the Interior’s Office of Insular Affairs (OIA) and with staff from the territorial governments, the Bureau of Economic Analysis (BEA) produces annual economic accounts for American Samoa, the Commonwealth of the Northern Mariana Islands (CNMI), Guam, and the U.S. Virgin Islands. The OIA provides funding for the work and facilitates interactions between BEA and the territorial governments.1

The purpose of this ongoing project is to provide data users with comprehensive, objective measures of economic activity for these four U.S. territories. Consistent measures of economic activity are critical for understanding the territorial economies and how they have developed over time. Without such measures, it is difficult for businesses and governments to make informed economic and financial planning decisions and for policymakers to assess the impacts of their decisions on growth. For the United States, BEA produces gross domestic product (GDP) and other related economic measures as part of its national income and product accounts (NIPAs); however, these estimates cover only the 50 states and the District of Columbia. Transactions with the territories are classified as transactions with the “rest-of-the-world.”

This year, BEA released new estimates of GDP for 2016 and revised estimates for 2013–2015.2 These estimates are shown in chart 1. For comparison, real GDP growth for the United States (excluding the territories) is also shown.

Highlights of the latest estimates of GDP for each territory are described below.

American Samoa

Real GDP decreased 2.5 percent in 2016 (table A.1.3).

  • The decline in the American Samoa economy reflected decreases in spending on construction and equipment; several investment projects in both the government sector and private sector either ended or entered their final stages during 2015.
  • Government spending decreased, reflecting a decline in investment spending by the territorial government (table A.1.4).3 Territorial government spending had been elevated in 2015 because of the telecommunication authority’s work to improve broadband capacity and coverage and the power utility’s work to rebuild the Satala Plant.
  • Business spending on construction and equipment continued to decrease, following major investments made by the tuna canning industry in previous years.

CNMI

Real GDP increased 28.6 percent in 2016 (table B.1.3).

  • The growth in the CNMI economy primarily reflected growth in gaming industry revenues and investments.
  • Exports of services was the largest contributor to economic growth in 2016, reflecting significant growth in visitor spending, particularly on casino gambling (table B.1.4).
  • Private fixed investment increased over 60 percent, reflecting construction of the casino resort in Garapan and other hotel construction on Saipan.

Guam

Real GDP increased 0.4 percent in 2016 (table C.1.3).

  • The growth in the Guam economy reflected increases in exports of services and consumer spending (table C.1.4).
  • Exports of services, which consists primarily of spending by tourists, grew for a third consecutive year. The increase reflected growth in visitor arrivals, particularly from Korea.
  • Consumer spending increased, reflecting growth in retail trade activity.

U.S. Virgin Islands

Real GDP increased 0.9 percent in 2016 (table D.1.3).

  • The growth in the U.S. Virgin Islands economy primarily reflected increases in inventory investment and exports of goods (table D.1.4)
  • Petroleum product and crude oil transactions accounted for the majority of the growth in inventory investment and in exports, reflecting the reopening of an existing oil storage terminal on St. Croix. A new operator took ownership of the facility that was previously owned by Hovensa and, in 2016, began receiving shipments of petroleum.

New estimates of GDP by industry and compensation by industry for 2015 were also included in the 2016 GDP news releases for each territory. These estimates, along with GDP for 2016, are presented in detail in the accompanying tables.4

The methods used to derive the estimates of GDP and GDP by industry are summarized in the appendix “Summary of Methodologies.”

This project represents an important step toward achieving BEA’s and OIA’s long-term goal: to integrate these territories into the full set of U.S. NIPAs. A primary obstacle to realizing this goal is the lack of coverage of these four territories by most of the major surveys used by BEA to produce estimates of GDP and related economic measures.5 Until the territories are included in these surveys, BEA will continue to depend heavily on the assistance and information provided by each of the territorial governments and on continued support from OIA.

Other future enhancements to the estimates for the four territories (subject to data availability and funding) include developing supplementary measures that are included in the full set of the U.S. NIPAs, such as personal income and personal saving rates.

The methodologies used to estimate GDP and GDP by industry for American Samoa, the Commonwealth of the Northern Mariana Islands (CNMI), Guam, and the U.S. Virgin Islands are consistent with the methods used to estimate GDP and GDP by industry for the United States (excluding the territories). Information from the Economic Census of Island Areas was used to establish levels of GDP for each territory for 2002, 2007, and 2012; for other years, annual indicator series were developed and used to estimate the components of GDP and of GDP by industry.

Gross domestic product

Consumer spending. Personal consumption expenditures (PCE) consists primarily of purchases of goods and services by households.6 Economic census data on the consumer shares of sales by industry were used to benchmark the estimates of household purchases of most goods and selected services.

Annual growth rates for most goods were derived using data on imports of goods and, where available, sales by businesses. For American Samoa, the CNMI, and Guam, data on imports of goods were provided by the territorial government.7 For the U.S. Virgin Islands, data on imports of goods were available from the Census Bureau’s U.S. Trade With Puerto Rico and U.S. Possessions (FT895) and U.S. International Trade in Goods and Services (FT900).8

Estimates that were not benchmarked to economic census data included housing services, utilities services, and financial services, which were estimated independently. Housing services were estimated using information on the number of occupied housing units and average rental rates reported in the Census of Population and Housing. Utilities services were estimated using revenue data reported by government-owned utilities and by the U.S. Energy Information Administration. Other services not covered by the economic census—such as financial services furnished without payment, insurance, and sales by government—were estimated using data from private trade sources and government financial reports.

Private investment. Private investment consists of spending on new fixed assets—equipment, software, and structures by private businesses—and improvements to existing assets. It also includes the construction of new residential structures and the improvements to these structures.9 Economic census data on businesses’ capital expenditures on fixed assets were used to benchmark the estimates of private fixed investment for each territory. Annual growth rates were derived using building permit data, construction industry receipts and wages, and imports of capital goods.

Net exports of goods and services. The estimates of exports of goods to the United States from the four territories reflected data from the Census Bureau’s U.S. Trade With Puerto Rico and U.S. Possessions (FT895). Estimates of exports of goods from American Samoa, the CNMI, and Guam to the rest of the world were based on information compiled by the territorial governments. Estimates of exports of goods from the U.S. Virgin Islands to the rest of the world were based on data from the Census Bureau’s U.S. International Trade in Goods and Services (FT900).

Estimates of imports of goods for American Samoa and the CNMI were based on values or quantities of imported commodities reported by the territorial governments. For the U.S. Virgin Islands, estimates of imports of goods reflected data from the FT895 and FT900. For Guam, data on imports of goods are limited, particularly after 2015; the available data were supplemented with other information reported by the Guam government, including sales by businesses.

Information on imports of services and on exports of services other than tourism was limited. Estimates of exports of tourism services for American Samoa were based on visitor arrival data provided by the territorial government and the Federal Aviation Authority. Estimates of exports of tourism services for the CNMI and Guam were based on survey data on tourist expenditures and visitor arrivals provided by the territorial government visitors’ authorities. For the CNMI, these data were supplemented with casino gambling revenues reported in company financial statements. For the U.S. Virgin Islands, the estimate of exports of tourism services was based on expenditures of cruise ship passengers available from the Florida-Caribbean Cruise Association, total visitor expenditures provided by the Virgin Islands Bureau of Economic Research, U.S. Virgin Islands visitor exit survey data, and gross business revenue data for select industries.

Government consumption expenditures and gross investment. The estimates of government expenditures were prepared for the territorial government sector and for the federal government sector. The primary sources of information for the territorial government estimates were financial statements of the primary government and of the government component units. The primary data sources for the federal government estimates were the Census Bureau’s Consolidated Federal Funds Report and the Federal Procurement Data System.10 Information on military pay was provided by the Department of Defense.

Estimates of real GDP. Inflation-adjusted estimates of total GDP and its components were derived within a chain-type Fisher index framework.11 For most of the detailed components of GDP, inflation-adjusted estimates were calculated by deflating each component using an appropriate price index. Consumer price indexes produced by each territorial government were used to deflate most of the detailed components of PCE. Inflation-adjusted estimates for most components other than PCE were calculated using U.S. prices from the U.S. Bureau of Labor Statistics.

GDP by industry

Current-dollar estimates. The estimates of GDP by industry were prepared for broad industry groups using a methodology that was developed to incorporate data from the Economic Census of Island Areas. Current-dollar value added for most private industries was extrapolated using indicators such as gross business revenues and compensation. For select private industries, data were available to separately extrapolate gross output and intermediate inputs. These industries included the manufacturing sector in American Samoa and the CNMI and the goods-producing sector in the U.S. Virgin Islands. Current-dollar value added for the government sector was prepared for the territorial government sector and the federal government sector; the primary sources of information were the data sources identified in “Government consumption expenditures and gross investment.”

Real estimates. Inflation-adjusted estimates of GDP by industry were derived within a chain-type Fisher index framework. For most industry sectors, the statistics on chained-dollar value added were prepared using the single-deflation method. Under this method, current-dollar value added of an industry is divided by a gross output price index.12 For industries for which data were available to separately estimate gross output and intermediate inputs, a double-deflation method was used. Under the double-deflation method, current-dollar gross output and current-dollar intermediate inputs are deflated separately, and real value added is computed as the difference between real gross output and real intermediate inputs. Price indexes and other value and quantity data produced by each territorial government, in addition to U.S. prices, were used in the deflation of value added, gross output, and intermediate inputs.

Compensation of employees. Information on payroll and fringe benefits from the economic census was used to benchmark the estimates of compensation by industry. For American Samoa, the CNMI, and Guam, annual growth rates were based on payroll data from a number of sources, including wage information from the Census Bureau’s County Business Patterns and administrative and survey-based wage data provided by the territorial governments. For the U.S. Virgin Islands, wage information from the U.S. Bureau of Labor Statistics Quarterly Census of Employment and Wages was used.

Aya Hamano of the Bureau of Economic Analysis (BEA) and Wali Osman of the Office of Insular Affairs (OIA) oversaw the preparation of the territorial economic accounts for American Samoa, the CNMI, Guam, and the U.S. Virgin Islands.

From BEA, Christina D. Hovland-Battikha and Erin M. Ludlow prepared the estimates for all four territories. Brian C. Moyer, Director of BEA, provided overall supervision. Other significant contributors from BEA were Benjamin Kavanaugh and Andrew J. Pinard.

The Economy-Wide Statistics Division of the U.S. Census Bureau provided data from the Economic Census of Island Areas.

From the U.S. Department of the Interior, Nikolao Pula, Director of OIA, provided support throughout the project. Lydia Faleafine-Nomura of OIA served as liaison between BEA and the American Samoa government.

BEA would also like to thank the governor’s offices of the four territories for their contributions. Governor Lolo M. Moliga and Lieutenant Governor Lemanu P. Mauga of American Samoa, Governor Ralph D.L.G. Torres and Lieutenant Governor Victor B. Hocog of the CNMI, Governor Eddie B. Calvo and Lieutenant Governor Ray S. Tenorio of Guam, and Governor Kenneth E. Mapp and Lieutenant Governor Osbert E. Potter of the U.S. Virgin Islands contributed guidance and support throughout the project.
