      <abstract xml:lang="ru">
        <p>В братской семье республик великого Советскою Союза Армянская ССР по территории самая небольшая — всего около 30 тыс. км², население ее 2,5 млн. человек. Это составляет всего 0,13% территории и 1% населения Советского Союза. Однако благодаря исключительному богатству недр Армении минеральным сырьем удельный вес Армянской ССР в запасах и добыче ряда важных металлических и неметаллических полезных ископаемых значительно выше этих цифр.</p>

        <p>In the fraternal family of republics of the great Soviet Union, the Armenian SSR is the smallest in territory — only about 30 thousand km², and its population is 2.5 million people. This is only 0.13% of the territory and 1% of the population of the Soviet Union. However, owing to the exceptional richness of Armenia's subsoil in mineral raw materials, the share of the Armenian SSR in reserves and production of a number of important metallic and non-metallic minerals is much higher than these figures.</p>
